摘要

The conventional finite-difference time-domain method applies discretization to both space and time, leading to the discrete solutions in both space and time. In this letter, we propose a wave-equation-based spatial finite-difference method that discretizes a solution domain in space but not in time. It is based on the spatial eigen decompositions of the field solutions without approximations to t...
