摘要：
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.
