The EMP cortically induced current in coaxial cables near the ground is analysed by using Finite-Difference Time-Domain method in this paper. 本文采用時(shí)域有限差分法，分析電磁脈沖作用下，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(shí)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(jìn)行了定量研究。
