【摘要】 在研究瞬变电磁场的奇点展开法中,散射物体的自然频率(极点)是一个非常重要的参数。以往人们都用迭代法或围线和分法计算物体的自然频率。本文采用Kuhn法,在不需任何初值假设的情况下,用不多的计算时间求出了精度很好的细线导体的极点。更多还原

【Abstract】 When the problem of the transient electromagnetic scattering of a body is studied by using singularity expansion method(SEM), the natural frequency (pole)of the body is a very important parameter. The SEM poles have been calculated theoretically by using the iterative method and contour integral method so far. In this paper ,Kuhn’s algorithm is employed to obtain the poles of a thin wire conductor without any assumption of the initial value.更多还原
