Double-stacked hyperbolic metamaterial waveguide arrays for efficient and broadband terahertz quarter-wave plates
We demonstrate how it is possible to achieve weak dispersion in the phase delay between two orthogonal polarization states by using double-stacked hyperbolic metamaterial (HMM) waveguide arrays. The weak dispersion in the phase delay originates from the different signs of phase delay from the two di...
