Abstract
- We show that the linear polarization state of electromagnetic waves at terahertz frequencies can be perfectly rotated to its orthogonal direction by an alternative design of anisotropic dielectric meta-reflectarrays. Numerical results demonstrate that the reflection coefficient converting to cross polarization after reflection can be as high as ~100% from 0.75 THz to 1.0 THz. The designed system does suffer little energy loss due to the absence of the metallic metamaterial unit cells and the absorptive dielectric. [ABSTRACT FROM AUTHOR]
