Abstract

We design terahertz wave reflective polarizer that operates over a wide terahertz wavelength range and is based on a periodic bilayer structure. The structure is characterized by transfer matrix calculations. Results of simulations show that the mirror is highly reflecting for incidence angle θ ≤ 60°and TE as well as TM polarization in the wavelength range between 541.6 μm and 574.2 μm (i.e. frequency band between 522.5GHZ and 533.9 GHZ). As the incidence angle increases this reflection band blueshifts for both TM and TE polarizations.
