Electromagnetic modeling of passive circuit elements in MMIC

In this article, an approach is presented to compute the scattering parameters of the ferrite-loaded waveguide discontinuity using the finite-element method (FEM) and perfectly matched layers (PMLs). The propagation constants of a uniform ferrite-loaded waveguide are first calculated to validate the proposed approach. Then a 2D ferrite-loaded discontinuity problem is computed to further confirm the accuracy of the approach. Finally, several 3D discontinuity results are given to show the efficiency and generality of the approach.

“…As an unparalleled feature, this deembedding technique allows one to consider the whole feed line section, ranged between the impressed source and the discontinuity under modeling, as an individual two-port error box. There is no requirement to constitute a uniform feed line beforehand with known transmission parameters, i.e., phase constant and characteristic impedance, as required in many of other numerical deembedding techniques [5][6][7][8][9].…”

“…Of many available MoM algorithms, two distinctive deembedding techniques [5,6] were developed and utilized for deembedding of planar discontinuities with uniform feed lines. In [5], standing-wave field amplitudes were calculated at the three different points along the uniform feed line to determine scattering matrix of the core circuit block.…”

A numerical short-open calibration technique is applied to deembedding of planar discontinuities with periodically perturbed nonuniform feed lines in the full-wave method of moments (MoM) algorithm. Different from the other deembedding techniques that are based on the assumption of uniform feed lines, this proposed technique exhibits an unparalleled capability on modeling of planar circuits with nonuniform feed lines. To demonstrate this feature, the open and gap discontinuities are modeled under periodically nonuniform feed configuration, and the effective per-unit-length transmission parameters of slow-wave and electromagnetic bandgap structures are extracted from the full-wave MoM simulation. Two periodically nonuniform microstrip-line resonator circuits are modeled and then confirmed by EM simulators and measurement.
