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.

SMITH CHART DESIGNED ON A CAKE WITH TECHNICAL MEASUREMENS for the first time in the WORLD

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. The team Designed Smith Chart on a Cake Smith Chart design on a Cake Smith Chart design on a Cake Dr S Raghavan Senior Professor, ECE dept., N I ...

FATHER OF RADIO WHO MADE INDIA PROUD

JC BOSE PEN SKETCH JC BOSE is the FATHER OF RADIO (and NOT MARCONI) of the world. Marconi himself had lots of regard for JC BOSE. He played with 65 GHz so many years before, he has done work on METAMATERIAL as well as FSS. This is the pen sketch drawn in an hour by Ms. K arri Sri Siddhi , III year ECE, NIT T. MS KARRI SRI SIDDHI (along with 2 more girls) was the first to draw "THE SMITH CHART" in the form of RANGOLI(ATHAPOO, KOLAM) IN THE 50 YEARS HISTORY OF R.E.C./N.I.T., TRICHY as a token of gratitude to the MICROWAVE LIFETIME ACHIEVER DR S RAGHAVAN. Incidentally One M.TECH. BATCH for the first time in the world designed smith chart cake(can be found in google and yahoo if searched "smith chart".

VALENTINE DIAGRAM and MICROWAVE TECHNOLOGY

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...
