Analytical study of mismatched complementary media

An analytical framework based on multiple scattering theory is established for analyzing the mismatched case of complementary media (CM) interacting with arbitrarily situated obstacles. The CM-based devices of a superlens and superscatterer are discussed. The cancellation mechanism of the mismatched CM is studied. In addition, numerical results are provided for illustration. Detailed analysis shows that optical cancellation effects rely on specific conditions. Specifically, we studied the mismatched CM with perfect electrical conductor objects and presented its equivalence models. (C) 2016 Optical Society of America
