通常在时域有限差分(FDTD)技术中，当场在静止物体周围传播并且可能在这些物体内部传播时，在时间域模拟中对静止物体进行建模。本文介绍了一种利用FDTD技术模拟电磁场和运动目标的方法。通过使用介电近似和中步场运动的技术，可以用FDTD技术来模拟物体的运动。本文在一维域中说明了这些原理，并给出了二维域的扩展和结果。
Normally in the finite difference time domain (FDTD) technique, stationary objects are modeled in a time domain simulation as a field propagates around them, and possibly inside these objects. This paper illustrates a method in which EM fields and a moving object can be modeled using the FDTD technique. By using a technique of dielectric approximation and intermediate step field movement, it is possible to model the movement of objects by the FDTD technique. This paper illustrates these principles in a one-dimensional domain with extensions and results for 2D as well.
