Abstract

An artificial surface with asymmetric reflection properties is presented. By covering a metalground plane with periodic metal-dielectric composite textures, the electromagnetic reflectionproperties can be altered. By tuning the individual lattice of a periodic mushroom-typetexture to vary the surface impedance, a surface with graded reflection phases as a function ofposition can be designed. Applying a linear gradient in the reflection coefficient phase alongthe face, the proposed surface is electromagnetically inclined, even though physically flat.For the whole ranges of the incident angle, this metasurface reveals asymmetric reflectionproperties contrary to the Law of Reflection. The reflection patterns from the surface, theboundary condition, and the relation between the incident angle and the reflection angle arepresented.
