He developed an apparatus for generating ultra short electro-magnetic waves and studied their quasioptical properties. He was said to be the first to employ a semiconductor like galena as a self recovering detector of electromagnetic waves. Bose published three papers in the British magazine, ‘The Electrician’ of 27 Dec. 1895. His invention was published in the ‘Proceedings of The Royal Society’ on 27 April 1899 over two years before Marconi’s first wireless communication on 13 December 1901. Bose also invented highly sensitive instruments for the detection of minute responses by living organisms to external stimulii and established parallelism between animal and plant tissues.
