Abstract:The microwave dielectric constant of strontium titanate ceramic dispersed in the polyethylene matrix is studied by powder mixture equations in this article. The experimental dielectric constant values of the mixtures are compared to the theoretical curves of five published mixing rules. A new empirical mixture equation is proposed. The dielectric constant of pure strontium titanate is then estimated by these mixing laws from the dielectric constants of composites of various filler concentrations. The theoretic… 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.
