AGORA: Adaptive Generation of Orthogonal Rational Approximations for Frequency‐Response Data
International Journal of Circuit Theory and Applications, Volume 53, Issue 10, Page 5751-5759, October 2025.This paper introduces the adaptive generation of orthogonal rational approximations (AGORA) method for rational function approximation of measured or simulated microwave network parameters. AGORA allows estimating the model order for a given error tolerance and does not require any initial estimates or adjustment of hyperparameters. ABSTRACT This paper
