http://www.gillespieeyecare.com/ Web摘要： A bianisotropic metasurface design is proposed for extending the Brewster effect to arbitrary angles and polarizations. The metasurface is synthesized using the surface susceptibility tensor and Generalized Sheet Transition Conditions (GSTCs) synthesis method, and is demonstrated by GSTC-FDFD simulation.

WebRectangular Brewster windows are uncoated substrates used in an optical system at Brewster’s angle, the angle at which p-reflectance drops to zero. This can be calculated from: θ B = tan-1(n) where θ B is Brewster’s angle and n is the material’s index of refraction. When used in a laser cavity, a Brewster window causes polarized laser ... WebBrewster's angle is also known as the polarization angle, and it is the angle of incidence at which an unpolarized EM wave (containing equal amounts of vertical and horizontal polarization, Fig. 2.9) separates into a vertically polarized EM wave that is transmitted through a surface, leaving the surface reflection with only the horizontal …
