摘要

1.Introduction There is a significant gap between atmospheric space and undersea space for wireless radio transmission.The interface between air and seawater is a barrier to prevent radio wave trans-mission across the boundary.This is because seawater is an electri-cally conducting medium,and radio waves suffer significant absorptive attenuation there.As a result,there is no internet,reli-able mobile communication,high-quality video,and long-distance duplex wireless communication in the underwater world of oceans.It is pitiful since the oceans share 71％of the surface of our planet and are of great importance to our economy,ecology,and living environment.
