Abstract

With growing exploitation of marine resources, underwater communication issues have become imperative. In this letter, the total-field scattered-field source (TSS)-finite-difference time-domain (FDTD) method based on graphics processing unit (GPU) is used to investigate the low-frequency field distribution of electromagnetic waves in a stratified marine environment. We specifically investigate the impact of the noncontinuous and continuous waved seafloor topographies on the electromagnetic field distribution generated by an underwater low-frequency horizontal electric dipole and study the effect of incident wave frequencies on the seafloor field distribution. In addition, we also quantitatively evaluate the acceleration efficiency of the GPU-accelerated TSS-FDTD method for both two-layered and three-layered media.
