Multi-dimensional Cauchy method and adaptive sampling for an accurate microwave circuit modelling
S.F. Peik, Raafat R. Mansour, Yin-Shan Chow · 2002
The paper presents an effective generic approach for CAD design of microwave circuits. We extend the one-dimensional Cauchy method for frequency response interpolation to a multi-dimensional Cauchy interpolation with respect to both frequency and physical dimensions. The paper also demonstrates the feasibility of applying adaptive sampling to the multi-dimensional rational function expansion. Two examples are given to verify the validity of the proposed approach.
