APPLICATION OF SWITCH-ON FUNCTIONS IN THE 2-D FDTD MODELING TIME-HARMONIC ELECTROMAGNETIC SCATTERING

摘要: 在用时域有限差分(FDTD)方法模拟稳态电磁散射时,为了减小稳态建立过程中的冲激效应,缩短建立稳态所需时间,本文引入了开关函数,并给出几种开关函数下FDTD的稳态建立过程。Abstract: When the time-harmonic electromagnetic scattering is modeled via the finite-difference time-domain (FDTD) technique, an additional switch-on function is introduced in order to reduce the ringing phenomenon for initial transient process in FDTD calculation. Some examples are given to demonstrate the feasibility.
