摘要

In this work, a combination of 2D and 3D quasi-static Green's functions (GF) is proposed for extending the frequency range validity of the quasi-static approximation. It is shown that 3D-GF is very accurate at low frequency, whereas 2D-GF is more suitable at higher frequencies because it is the actual solution of the transverse electromagnetic (TEM) propagation mode. The mixing of both GFs is controlled through the ratio of the main size of the device versus the wavelength at the given simulation frequency. Numerical examples are compared with experimental data for different passives in a broadband frequency range.
