International audienceThis article explores an optimization procedure for microwave filters and multiplexers. The procedure is initialized by a classical filter synthesis based on a segmented electromagnetic synthesis that provides the basic dimensions of the structure. The optimization loop, which combines a global electromagnetic analysis and a coupling identification, improves the structure response compared to an empirical optimizatio
In this paper, we used a topology gradient method coupled with a finite element method in order to optimize the shape of a microstrip component. We appended a 2-D distribution ofmetal on the substrate and tried to optimize its form by taking benefits of the topology gradient method. The concept of topology gradient using a numerical method is given in this article, and finally, the results of using this approach in the context ofmicrowave component optimization is shown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
