• In spring 1899 Braun, accompanied by his colleagues Cantor and Zenneck, went to Cuxhaven to continue their experiments at the North Sea.
• Basically distinct from the " free-space " waves, such as those studied by Hertz in his UHF experiments, are Zenneck waves.
• "' Jonathan Adolf Wilhelm Zenneck "'( April 15, 1871  April 8, 1959 ) was a physicist and electrical engineer.
• The Kugelbake was also the spot where amateur radio pioneer Jonathan Zenneck experimented with radio communications between the Mainland and ships at sea during the winter of 1899 1900.
• The Sommerfeld-Zenneck wave is a non-radiative guided electromagnetic wave that is supported by a planar or spherical interface between two homogeneous media having different dielectric constants.
• Zenneck improved the Braun cathode ray tube, by adding a second deflection structure at right angles to the first, which allowed two-dimensional viewing of a waveform.
• Arising from original analysis by Arnold Sommerfeld and Jonathan Zenneck of the problem of wave propagation over a lossy earth, it exists as an exact solution to Maxwell's equations.
• After studies of mathematics and physics in Freiburg and Munich ( with Arnold Sommerfeld ), under Jonathan Zenneck he wrote a thesis on partial reflection of radio waves in an ionospheric layer.
• The plants were finally placed for research work at the Physical Institute of the Technical University of Munich, where under the direction of Professor J . Zenneck, the first German ionosphere research station developed.
• At this frequency, the silver behaves approximately as a perfect electric conductor, and the SPP is called a Sommerfeld-Zenneck wave, with almost the same wavelength as the free-space wavelength . ]]
• The article Wireless power transfer has been a battleground for years due to extremely persistent efforts to insert an alternate theory that around 1900 Nikola Tesla transmitted electric power around the world using something called a Zenneck wave.
• Prominent prisoners included Count Albrecht von Montgelas, Dr . Karl Muck, conductor of the Boston Symphony Orchestra, Dr . Ernst Kunwald, conductor of the Cincinnati Symphony Orchestra, Professor Richard Benedict Goldschmidt, biologist Dr . Isaac Strauss, and Professor Zenneck.
• Note that the radiation Tesla was about to utilize at Wardenclyffe was not Hertzian in nature but in fact Zenneckian, as he was openly saying that he was dismissing Hertzian radiation for far-distance wireless energy transmission and going for Zenneck waves instead, and thus the waves would be propagating basically in plasma, in Tesla's case particularly using air, water, and the planet earth itself as natural media conductors ( basically like solar wind plasma ).
