What are the properties and applications of Zenneck surface waves?

Zenneck surface waves are electromagnetic waves that travel along the interface between two different mediums, such as air and a conductor. These waves have unique properties, including low attenuation and the ability to propagate over long distances.

One key application of Zenneck surface waves is in wireless communication, where they can be used to transmit signals over large areas with minimal signal loss. They are also being studied for potential use in underground communication and sensing systems.
