Abstract

To optimize the dispersion of the fundamental weaker hybrid implicit explicit in the finite-difference time-domain method, a lower dispersion method is proposed by optimization parameters. A series of important parameters related to the numerical dispersion is analyzed. Results show that the low-dispersion method improves the dispersion property significantly without changing the stability condition. In addition, an antenna example is adopted and verifies the effectiveness of the proposed low-dispersion method. Simulation results of various methods above are in very good agreement with the experiment.

优化的低色散基波弱化 HIE-FDTD 方法

为了优化时域有限差分法中基本弱混合隐式显式的色散，提出了一种优化参数的低色散方法。分析了与数值色散有关的一系列重要参数。结果表明，低色散方法在不改变稳定性条件的情况下，显著提高了材料的色散性能。最后，通过天线算例验证了该方法的有效性。上述各种方法的仿真结果与实验结果吻合得很好。

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.
