摘　　要：高功率微波(high-power microwave,HPM)天线作为HPM系统与外界交互能量的通道,其对HPM系统的性能具有重要的影响。设计HPM天线时,受制于有限的测量手段和高昂的实验成本,难以通过实验方法对HPM天线性能进行分析。相较于实验方法,高效精确的电磁仿真方法是分析HPM天线性能最有效、最经济的研究手段。目前,HPM天线主流电磁仿真方法包括:全波仿真方法、高频渐近方法以及混合方法。本文对近年来HPM天线电磁仿真方法的新进展进行了介绍,总结了各种电磁仿真方法的优缺点,可为HPM天线性能仿真方法的选取提供思路。As channels for exchanging energy between high-power microwave systems and the outside world,the high-power microwave antennas have a significant impact on the performance of high-power microwave systems.When the high-power microwave antennas are designed,it is difficult to analyze the performance of high-power microwave antennas through experimental methods,since the measurement methods are limited and the experimental costs are high.Compared to experimental methods,efficient and accurate electromagnetic simulation methods are the most effective and economical research means to analyze the performance of high-power microwave antennas.At present,the mainstream electromagnetic simulation methods for high-power microwave antennas include full wave simulation methods,high-frequency asymptotic methods and hybrid methods.This paper introduces the new progress of electromagnetic simulation methods for high-power microwave antennas in recent years,summarizes the advantages and disadvantages of electromagnetic simulation methods,and provides ideas for the selection of simulation methods for high-power microwave antennas.
