Webangle of incidence reflectivity is close to zero R ~ 0. This angle is called the Brewster's angle θ and is associated with the refractive index n of the material through equation 1 (2): Θ B = arctan (n/n 0) where n 0 is refractive index air (n 0 =1). To determine the values of the refractive index, we measured Webcrystal, in its simplest form, can be realized as alternating layers of two dielectrics in one dimen-sion (1D). 2 Such 1D photonic crystal structures can be realized using dielectric materials for the THz spectral range to exhibit bands in their spectral response with very high reflectivity. 3 7 how do you clean shoes
