本文给出一个实际求解偏心特种截面传输线问题的、建立在明晰物理概念上的方法。该方法的实质是,将一些偏心特种截面传输线分解为比较简单的规则图形,从而使边值问题的求解工程化。为了说明该方法的具体运用,本文计算了在电磁工程中广泛应用的圆形内导体槽形传输线和方形内导体槽形传输线,通过与有关文献的数值比较和理论分析,证实其准确性和实用性。
In this paper, we present a method that is based on a clear physical concept that actually solves the problem of eccentric cross-section transmission lines. The essence of this method is to decompose some eccentric special cross-section transmission lines into simpler regular graphs so as to engineer the solution of boundary value problems. In order to illustrate the concrete application of the method, this paper calculates the circular inner conductor slot transmission line and the square inner conductor slot transmission line, which are widely used in electromagnetic engineering. The numerical comparison and theoretical analysis with the relevant literature prove that the transmission line is accurate and practical Sex.
