Abstract: This work presents a theoretical–experimental study of a refractive index (RI) sensor based on lossy mode resonances (LMRs) generated with a side-polished low-index polymer optical fiber.

Abstract: This paper presents a novel wideband low-profile linear-to-circular polarizer based on high refractive-index metamaterials in the X band. The proposed design is a multilayer structure that ...
