| Popis: | We present a system-identification procedure applied to a crosstalk problem, which can be accurately analyzed by an in-house full-wave solver based on the method of moments (MoM). Given a relatively few frequency-samples of the crosstalk current, we demonstrate that it is feasible to estimate a reduced-order model of the continuous frequency dependence, where the frequency band of interest corresponds to an electrical size of the system that ranges roughly from 0.005 to 2.7 wavelengths. The estimated low-order model of the frequency response takes the form of a Pade approximant and it yields an accurate representation when compared to the reference frequency-response, as it is computed directly by the MoM solver. In addition, the low-order model can be evaluated at an extremely low computational cost and it provides useful information such as resonance frequencies and their quality factors. For the system analysis of a real-world device, the low-order model can serve as a computationally powerful and accurate representation of the electromagnetic response for a subsystem that features full-wave phenomena that otherwise could be too challenging to describe at a system level. |
