Waveguide – Jagadish Chandra Bose researched millimetre wavelengths using waveguides, and in 1897 described to the Royal Institution in London his research carried out in Kolkata. [ 265 ] Phantom connectivity, a system for providing a higher level security to data communication in computer networks developed by ISRO .
Most Genius Indian in the World Forever, Best Student of Indian Bengali Physicist Sir Acharya Jagadish Chandra Bose, when he (Satyendra Nath Bose) was a Reader (later made Professor by the recommendation of Albert Einstein) at the University of Dhaka (Bengal, now in Bangladesh/East Bengal), he developed the foundation of the Bose–Einstein ...
Crescograph, Bose Institute, Kolkata. A crescograph is a device for measuring growth in plants. It was invented in the early 20th century by Jagadish Chandra Bose. The Bose crescograph uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant (or its roots). It was able to record at magnifications of ...
Millimetre wave communication was first investigated by Jagadish Chandra Bose during 1894–1896, when he reached an extremely high frequency of up to 60 GHz in his experiments. [33] He also introduced the use of semiconductor junctions to detect radio waves, [34] when he patented the radio crystal detector in 1901. [35] [36]
In November 1894, the Indian physicist, Jagadish Chandra Bose, demonstrated publicly the use of radio waves in Calcutta, but he was not interested in patenting his work. [84] Bose ignited gunpowder and rang a bell at a distance using electromagnetic waves, [85] confirming that communication signals can be sent without using wires. He sent and ...
