Early years
Zenneck was born in Ruppertshofen, Württemberg.
In 1885, Zenneck entered the
In 1894, Zenneck conducted zoological research (Natural History Museum, London). Between 1894 and 1895, he served in the military.
Middle years
In 1895, Zenneck left zoology and turned over to the new field of radio science, He became assistant to
Zenneck analyzed solutions to Maxwell's equations that are localized around an interface between a conducting medium and a non-conducting medium. In these solutions, the electric field strength decays exponentially in each medium as distance from the interface increases. These waves are sometimes called Zenneck waves. Zenneck analyzed plane wave solutions having this property; he also analyzed solutions with cylindrical symmetry having this property.[3][4]
