摘要
提出了一种用切比雪夫展开来逼近索末菲被积函数的方法,经上机验算,仅取5项,就能获得满意的精度,该方法特别适用于需要大批量索末菲积分值的分层媒质中的电磁场问题.
A kind of approximating Sommerfeld ingrand function method using Chebyshevexpansion is presented.Satisfied accuracy is acquired only five terms and checked by thenummerical integral results.The proposed method is suitable to electromagnetic field problemsrequesting a lot of Sommerfeld integral values.
