The aim of this study is to analyze and evaluate the efficiency of wireless power transfer under different types of water, in this work, a preliminary investigation about the behavior of a parallel plate capacitor immersed in the seawater is presented. The reference structure consists of two square copper parallel plates with a side of 18 cm. Four media have been considered (air, de-ionized water, seawater and tap water); the distance between the plates has been varied from 0.5 cm to 50 cm per each medium, and the transmission coefficient of the capacitive coupling model is recorded for each case. The measurements are performed in the frequency range 30KHz - 50 MHz By analyzing the results, the tendency of the coupling is more capacitive in the case of deionized water and tap water while it is more resistive in the case of seawater because of the significant connectivity of the salt water, the maximum efficiency noted to be at the frequency around 2.5MHZ an equivalent circuit model has been carried out and some considerations about the power transfer mechanism in capacitor-based (capacitive coupling) structure in the seawater have been deduced.
