Microwave engineering and its important role in India´s development

Summary form only given, as follows. Generation, detection and propagation of radio frequencies has been a subject of enthusiastic study in the physics departments of Universities since the beginning of the last century. Jagadish Chandra Bose was the first to demonstrate in public in 1895 remote control by radio by detonating a device placed faraway. This event and Marconi´s experiments in England generated considerable interest among the physicists all over India.
