Simulation and analysis of current field based underwater communication system with arrayed polar plates

Abstract： Current field communication represents a wireless technology that propagates through underwater environments by conducting electric current. Conventional underwater electromagnetic wave communication encounters challenges such as significant signal attenuation, intricate antenna structures, and installation difficulties. To address these issues, this study integrates the theory of underwater current field propagation and proposes an underwater communication system based on an array of polar plates.The electric field model of the array polar plate is established utilizing the finite element software Comsol. Frequency domain analysis is employed to simulate the electric field and potential distribution of the 1×4 array cut surface. Additionally, a comparative analysis of signal reception effectiveness is conducted between 1×4 and 1×2 arrays. Building upon this, the impact of six sets of positive and negative wiring methods on signal reception strength is analyzed. Transient time-domain analysis is then applied to simulate changes in input and output waveforms.Experimental results validate that enhancing the number of array rows effectively improves communication without increasing transmit power. Moreover signal waveforms exhibit minimal alteration and maintain phase stability during transmission, thereby confirming the viability of underwater communication using arrayed polar plates. The findings of this research contribute a theoretical foundation for the development of a novel current field underwater communication system.
