完美导电物体上的电磁散射通常是由传入的电磁场引发的。众所周知,求解散射电场的经典边界元实现对于输入信号的频率并不是一致稳定的。本文的主题是开发一种稳定的边界元公式,该公式不会遭受所谓的低频击穿。通过数值例子验证了数学理论。版权所有 © 2012 约翰·威利父子有限公司
The electromagnetic scattering at a perfectly conducting object is usually initiated by an incoming electromagnetic field. It is well known that the classical boundary element implementations solving for the scattered electric field are not uniformly stable with respect to the frequency of the incoming signal. The subject of this article is to develop a stabilized boundary element formulation that does not suffer from the so‐called low‐frequency breakdown. The mathematical theory is verified by numerical examples. Copyright © 2012 John Wiley & Sons, Ltd.
