In which area did this French engineer and physicist, whose name became synonymous to one of a series of concentric prolate ellipsoidal regions of space between and around a transmitting antenna and a receiving antenna system, contribute significantly?
Fresnel zone A Fresnel zone ( ), named for physicist Augustin-Jean Fresnel, is one of a series of concentric prolate ellipsoidal regions of space between and around a transmitting antenna and a receiving antenna system. The concept is used to understand and compute the strength of waves (such as sound or radio waves) propagating between a transmitter and a receiver.
Guglielmo Marconi Guglielmo Marconi, 1st Marquis of Marconi ( ; ] ; 25 April 187420 July 1937) was an Italian inventor and electrical engineer known for his pioneering work on long-distance radio transmission and for his development of Marconi's law and a radio telegraph system. He is usually credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".
