A Physical Explanation of Angle-Independent Reflection and Transmission Properties of Metafilms/Metasurfaces

Abstract

In this letter, we illustrate that a metafilm (the two-dimensional equivalent of a metamaterial, also referred to as a metasurface) can be designed to have transmission and reflection properties that are independent of the angle of the incident wave. We show theoretically and discuss physically why this behavior occurs in certain metafilms. We show that by… (More)
