Abstract

In this letter, a 2-D parameter-optimized spatial finite-difference temporal differential (SFDTD) method is presented, referred to as the PO-SFDTD method. First, the dispersion characteristic of the conventional SFDTD method is demonstrated. To improve dispersion performance, we incorporate a weight parameter and utilize the central-difference approximation with four stencils for spatial discretization. Then, we develop a dispersion-controllable 2-D PO-SFDTD method. Numerical experiments validate that the proposed method can significantly reduce dispersion errors and optimize numerical dispersion according to specific requirements.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
