Abstract
Inverse design has attracted attention in recent years as an approach to synthesize complex electromagnetic structures, both in optical and microwave domains. As these structures grow in size and complexity, it becomes infeasible to solve the inverse problem with the aid of full-wave solvers. We present an algorithm that takes an arbitrary passive and reciprocal two-port microwave network defined by its S-parameter matrix, and breaks it down into an m-by-n grid of simpler two, three, and four-port interconnected networks. These blocks are simpler in nature, having fewer spectral features and thus more receptive to a traditional inverse design method, while the full grid still combines to produce the desired output. Each block is composed of a passive and reciprocal N-port network, where each component is a transfer function of variable order in Laplace domain. These blocks are combined in a grid, forming a cascaded S-parameter matrix which closely resembles the input. This method has the potential to reduce the total design space an inverse design algorithm has to search for, substantially speeding up computation.
