Keynote Speech Abstract:
Because of the high permittivity and conductivity of seawater, it is a big challenge to transfer radio wave in seawater over a long distance. In this talk, the research of developing antennas for seawater use is introduced. The electromagnetic performance of antennas for seawater use and propagation loss under seawater of extremely low frequency (ELF) and super low frequency (SLF) are investigated numerically and experimentally. The possibility of applications using radio wave in seawater is discussed.
