摘要

本文讨论了开放结构微带线的解决方案。本文试图找出变分法和谱域法在极低频率下的关系。本文推导了低频谱域方法的格林函数。利用伽辽金法得到了有效相对介电常数的计算公式。在直流时,横向电流密度为零。然而,为了得到准确的有效相对介电常数,需要同时使用纵向电流密度和归一化横向电流密度。

Low frequency microstrip analysis using the spectral domain approach and the variational method
This paper addresses the solution for the open structure microstrip line. This paper attempts to find the relationship between the variational method and the spectral domain approach at very low frequencies. In this paper, the Green's functions for the spectral domain approach at low frequencies are derived. The Galerkin's method is used to obtain the formula to calculate the effective relative dielectric constant. At DC, the transverse current density is zero. However, to get the accurate effective relative dielectric constant, both the longitudinal current density and the normalized transverse current density should be used.
