Study on the propagation characteristics of the electromagnetic wave across water film on the surface of the towed antenna

Based on Maxwell equations, the propagation characteristics of electromagnetic waves across the three layers of the air-water-film-towed cable propagation medium were analyzed, the effect of the antenna's proximity to the medium was proved, and the influence of the seawater film attached to the outside of the towed cable on the reception performance of the towed antenna was obtained, and the FEKO electromagnetic simulation software was used for example verification.
