A Study on the PML Absorbing Boundary Condition of the FDTDMethod for Rectangle Microstrip Antenna

将完全匹配层 (PML)吸收边界应用于微带结构中 ,对矩形微带天线进行了分析计算 ,给出了其时域和频域的仿真结果。结果表明 ,与传统的Mur边界相比 ,采用PML吸收边界具有反射小、馈源模型简单、收敛速度快等优点。

The Perfectly matched layer (PML) absorbing boundary condition is used in the FDTD analysis of microstrip structure. A detailed analysis of a rectangle microstrip patch antenna is presented, and the simulation results are given. It is shown that the characteristics of this new technique are smaller reflection, simpler model of source and faster convergence compared with Mur's absorbing boundary condition.
