Research on the Optimal Design of Polarization Conversion Metasurfaces

Polarization, as a fundamental characteristic of electromagnetic waves, is the locus of the tip of the electric filed at a given point as a function of time. The linear-to-circular polarization (LCP) conversion and cross polarization (CP) conversion, as two main branches of polarization manipulations, have been widely used in various fields, such as antenna designs, microwave communications, and anti-interference technologies.
