摘要

Simulation-inserted optimization (SIO) is a novel optimization method in electromagnetic (EM) field recently. Quasi-Newton has been proposed to replace decomposition of Upper/Lower matrices in Newton-based SIO with approximate inverse of Hessian matrix. This paper aims to apply the SIO using combined quasi-Newton method with Lagrangian method to optimize a four-order waveguide filter.
