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.
