Brewster angle for anisotropic materials from the extinction theorem

2231 Brewster angle microscopy

Purpose: The established methods for observing the morghnl-og;i nF the teer film a=~ based on ;nierfrrenc~ techniques. Since interference patterns are visible only in e pathologically thickened tear film, these techniques are not useful for the physiological tear film morphology. Methods: A ne;.approach is Brewster Angle Microscopy n-which allows the studv of ultra-thin films. In ophthalmology ...

Brewster angle for plasmonic gratings

In this paper, we analyze the transmission properties of metallic gratings at optical frequencies. In particular, we show that an inherently ultra-broadband tunneling mechanism may be obtained based on impedance matching between the guided modes supported by ultranarrow slits and freespace TM plane waves impinging at an oblique angle. This phenomenon is the analogous of the well-known Brewster ...

Brewster angle with a negative-index material.

The demonstration and confirmation of metamaterials with simultaneous negative permittivity and permeability, and thus a negative refractive index, has resulted in a surge of interest in the reflection and refraction phenomena at the interfaces of these so-called negative-index materials (NIMs). We present a systematic study of the Brewster angle, i.e., the angle of incidence at which no reflec...
