Enhancing Numerical Stability in Multiport Network Synthesis with Modified DK Method

This paper presents a modified Durand-Kerner (DK) method with the aim of improving the suitability for solving the Feldtkeller Equation, specifically in the context of high-order multiplexer synthesis. By refining the initial solution and iteration strategies of the classical DK method, our proposed approach effectively mitigates limitations associated with numerical errors in multiplexer synthesis. The method’s stability is evidenced through comparisons with alternative approaches.
