Rajeswari Chatterjee – The first Woman Scientist to pioneer the Field of Microwave Engineering in India

     Professor Rajeswari Chatterjee lived a fulfilled life as reflected in her own words “Lucky to be where I am” in her biography. Brilliant in studies,  professionally accomplished, sharp in intellect and memory, courageous and forthright in expressing  views coupled with a kind personality having deep concern for societal issues such as  caste discrimination and women’s education, her life spanning Jan.1922 to Sept. 2010, stands tall to inspire, particularly young women scientists and engineers.

       Rajeswari had her early education in a “Special English School” set up by her grandmother, Kamalamma Dasappa, in the ‘Mahila Seva Samaj’ in Basavanagudi, Bangalore. Kamalamma was one of the very first women graduates in the erstwhile Mysore State and had played a pioneering role in social reform and for the emancipation  of women. Growing up in a well-educated, broad-minded family environment, with her grandmother around as a catalytic agent and an inspiring model, Rajeswari, born intelligent, perhaps imbibed courage and forward-looking spirit that lasted throughout her life.

       Rajeswari joined the Central College, Bangalore, in 1939 where she received her B.Sc (Hons) and M.Sc degrees in Mathematics and Physics, both with first rank in Mysore University. She was awarded the Mummadi Krishnaraja Wodeyar Award for  securing  first rank in B.Sc (Hons), the M.T. Narayana Iyengar Prize and the Walters Memorial  Prize for obtaining first rank in M.Sc. After completing her M.Sc in 1943, she joined the Indian Institute of Science (IISc), Bangalore as a Research Student in the then Electrical Technology Department in the area of Communication.

During 1945-1947, there was an interim Government in Delhi to transfer power from the British to the Indians. This Government had announced scholarships to bright young Indians to pursue higher studies abroad. In 1946, Rajeswari was selected for that scholarship in the field of ‘Electronics and its applications’. With this, she got admission  to the University of Michigan in Ann Arbor, USA. Those days, when there were many restrictions on girls wanting to pursue higher studies, both in India and abroad, Rajeswari was determined. With indomitable courage, she set out on a long voyage in July 1947, by sea via Singapore which took 30 days to reach the U.S.A. At Michigan,  she completed  her Master’s degree from the Department of Electrical Engineering. Then, following the agreement with the Government of India, she underwent practical training for eight  months in the Division of Radio Frequency Measurements at the National Bureau of Standards in Washington D.C. In 1949, Rajeswari went back to Michigan to continue her studies leading to a Ph.D degree. With Professor William G. Dow, an authority in Electronics and Electrical Engineering those days as her thesis advisor, she completed her Ph.D early 1953 and returned to India soon thereafter.
        On returning to India, she joined the Department of Electrical  Communication Engineering at IISc as a faculty member. The same year, she married Sisir Kumar Chatterjee who was already on the faculty of the same department and whom she had known for some years. Soon, she came to be known as Mrs Chatterjee, rather than Dr Rajeswari Chatterjee! She was the only woman on the faculty of IISc and it was no smooth-sailing for her. She, along with S. K. Chatterjee, initiated teaching and research in the area of Microwave Engineering, for the first time in India. With total dedication and the limited resources available at that time, they built up a Microwave Laboratory for experimental research in the area. Several research students joined and closely worked with them, received valuable hands-on experience in the laboratory. To the students, they were not just research supervisors, but mentors who cared for them.
        Rajeswari, subsequently became a Professor and also held the position of Chairman in the Department of Electrical Communication Engineering. Besides teaching electromagnetic theory, electron tube circuits and microwave technology, she was very active in research. She guided 20 Ph.D students, published over 100 research papers and seven books in Microwave Engineering and Antennas. Her major contribution has been in the field of antennas, mainly for aircraft and spacecraft applications. For her contributions to Microwaves, she received several awards and honours. These include the Lord Mountbatten prize for the best paper from the Institute of Electrical and Radio Engineering, (UK), the J.C Bose Memorial prize for the best research paper from the Institution of Engineers, and the Ramlal Wadhwa Award for the best research and  teaching work from the Institute of Electronics and Telecommunication Engineers. She was also a Fellow of several professional engineering societies.  She retired as Professor  in 1982.
        Over the three decades of her career at IISc, Rajeswari distinguished herself not only for her research contributions, but also as a considerate and caring teacher. Students could easily approach her even for their personal problems and for help. For young women students, she was a role model, an inspiration to march ahead in profession in absolute simplicity.
       Besides science and engineering, Rajeswari had interest in history and on many issues concerning society. After retiring from IISc, she started working in social programmes, mainly with the Indian Association for Women’s Studies. She addressed issues of caste and gender discrimination, particularly concerning women from poor financial background. In her book ‘A Thousand Streams –  A Personal History’ published in 2003 by the Bharatiya Vidya Bhavan, she presented her personal reminiscences interspersed with historical events of those times with such clarity bringing out her interest in history and her phenomenal memory.
        Rajeswari is survived by a daughter, Indira Chatterjee, presently a Professor of Electrical and Biomedical Engineering at the University of Nevada, Reno, USA.

SMITH CHART DESIGNED ON A CAKE WITH TECHNICAL MEASUREMENS for the first time in the WORLD Smith Chart design on a Cake       Smith Chart is a pictorial chart through which one can calculate complicated Transmission line (HIGH FREQUENCY MICROWAVE CIRCUIT THEORY) computations. In a second numerical answers can be found. This will be useful in WIRLESS COMMUNICATIONS and other microwave communications. Microwave Integrated Circuit components can be designed. Matching can be done.Amplifiers and Oscillators design can be made easy. The chart was found by Ph.Smith during 1938. The M.Tech first year ECE students under the guidance of Dr S Raghavan, Professor, ECE dept., N I T Trichy came out for the first time with the novel idea of DESIGNING the same through the cake.

HELEN KELLER Helen Keller           HELEN KELLER- an international celebrity who has shown the light of the day to disabled and a prodigy is to be remembered on this ‘WORLD DISABLED DAY’. Helen Keller would not have been known to the world had she not lost both her sight and hearing at nineteen months of age due to scarlet fever. “The best and most beautiful things in the world cannot be seen or even touched. They must be felt with the heart”; this is what she has proved to the universe by her life. She practiced and wrote,” Although the world is full of suffering, it is full also of the overcoming of it”. Yes! Helen Keller overcame disabilities and worked to help others who were blind and deaf. she has shown millions of people that disability need not be the end of the world. Helen Keller was born on June27, 10 in Tuscumbia, Alabama... Through Alexander Graham Bell, inventor of the telephone and a teacher for the deaf a young teacher, Annie Sullivan of Perkins Institut


TECHNOLOGICAL PRINCIPLES ARE DERIVED FROM NATURE: VALENTINE DIAGRAM and MICROWAVE TECHNOLOGY VALENTINE DIAGRAM and MICROWAVE TECHNOLOGY Life will be colourful when the MATCHING between Life partners is PERFECT. Similarly the Microwave Technology which is the back bone of modern communication, space applications, and digital diagnostics of health care, Defence applications is said to work perfect if the MATCHING is good. In Microwave technology, MATCHING is referred by the term ‘Reflection coefficient’. For perfect Matching ‘Reflection coefficient’ should be ‘zero’ and ‘Transmission coefficient should be ‘one’. In general they are all called Scattering coefficients. A curve of scattering coefficients drawn on Smith Chart (tool to ease the parameter calculation) resembles the ‘Valentine diagram’. The commonality between Life and ‘Microwave technology’ as depicted by the enclosed chart (thanks to ‘Microwave 101’) is ‘MATCHING’ DR.S.RAGHAVAN SENIORMOST FACULTY IN ELECTRO
