摘要

采用时域有限差分(FDTD)方法对太赫兹光导天线进行了分析。为了减少计算量，在时域有限差分法中引入了子网格技术。与传统的时域有限差分方法相比，该方法的内存需求和计算时间分别减少了约70%和60%，同时保持了数值精度。

Analysis of a Terahertz Photoconductive Antenna Using the Subgrid FDTD Method

A terahertz photoconductive antenna is analyzed using the finite-difference time-domain (FDTD) method. To reduce the computational requirement, the subgrid technique is introduced into the FDTD calculation. The memory requirement and the computational time are shown to be reduced by about 70% and 60%, respectively, in comparison with the conventional FDTD method, maintaining numerical accuracy.
