摘要

本文介绍了一种基于时域有限差分法(FDTD)的高效功率幅值变换(PAT)技术，用于导波系统的电磁仿真。时域有限差分法由于时域特性，是分析谐波或非谐波信号激发下的导波问题最常用的数值EM方法之一。通过严格的推导，我们成功地解决了导波系统色散特性所带来的PAT挑战。仿真结果表明，该方法是准确、高效的。

Power-to-Amplitude Transformation (PAT) for the analysis of guide-wave system based on FDTD method

In this paper, we introduce one efficient Power-to-Amplitude Transformation (PAT) technique based on the Finite-Difference Time-Domain (FDTD) method for the electromagnetic simulation of the guide-wave system. Due to the time-domain characteristic, FDTD method is one of the most popular numerical EM methods to analyze the guide-wave problem excited by harmonic or non-harmonic signal. With the rigorous derivation, we have successfully solved the PAT challenge which is provided by the dispersive character of guide-wave system. The simulation results indicate the PAT technique is exact and efficient.
