The EMP cortically induced current in coaxial cables near the ground is analysed by using Finite-Difference Time-Domain method in this paper. 本文採用時域有限差分法，分析電磁脈衝作用下，地面附近同軸電纜所感應的外皮電流。
The effect of waveguide width on the propagation of self-collimated beams in photonic crystals is studied using the finite-difference time-domain method. 在此基礎上，運用時域有限差分法對自校準光束在有限寬的波導中的傳播行為進行了定量研究。
