Accelerated computing FDTD algorithm based on lossy dispersion medium
2017 International Applied Computational Electromagnetics Society Symposium (ACES)(2017)
Abstract
In order to reduce the consumed run time and enhance the calculation efficiency for analyzing the propagation properties of an underwater low-frequency electromagnetic wave, a novel approach of modelling the sea with a lossy Drude dispersive medium is proposed. The numerical results of three cases verify the accuracy and validity of the proposed approach.
