An Improved Cubic Polynomial Method for Interpolating/Extrapolating MoM Matrices Over a Frequency Band
By
Progress In Electromagnetics Research, Vol. 117, 267-281, 2011
Abstract
The inter/extrapolation accuracy of the cubic polynomial method has been improved by optimizing three frequency samples for frequency-sweeping in the method of moments (MoM). In the method, the frequency samples are optimized by minimizing the global maximum of the polynomial component at the stationary points and two terminal points of the frequency band. The optimal frequency samples can be expressed as analytical forms of the two terminal points. Numerical examples are presented to validate the proposed method through comparison with the Pad\'{e} approximation.
