A new technique for computing the response of a line of finite length excited by HF electromagnetic fields

An effective method to evaluate the field coupling to a line of finite length has been presented in this paper. It allows analyzing structures typically solved by means of the TL method even when the assumptions about the absence of the common mode current and about the TEM (or quasi-TEM) propagation mode (which implies the constraints on the line transverse dimensions with respect both to the line length and to the minimum field wavelength) are disregarded.
