Loss analysis of contactless power transmission in seawater

This paper describes about power loss of Contactless Power Transmission (CPT) in seawater. Power transmission experiment was done in saline water, deionized water and air. The antennas are placed in the fish tank which is filled by liquid. Experimental results show that transmission efficiency in saline water is approximately 5% lower than that of in air. In saline water, loss that is caused by salinity of water appear on transmission loss. This loss is caused by the complex dielectric constant and the conductivity of saline water.
