Abstract:In this article, a novel coupling method which could easily change the coupling nature between two TE 01d -mode dielectric resonators (DRs) is presented. This method is based on electric field orientation of DR operating in TE 01d -mode, through altering the direction of the coupling structure in one DR, the coupled electric field orientation in the other DR would be changed along with the coupling nature between two resonators. To prove this method, two filters using cascaded quadruplet coupling structure hav… Show more
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.
