brewster

calculates Brewster and critical angles

Calling Sequence

[thb,thc] = brewster(na,nb)            (isotropic)
[thb,thcTE,thcTM] = brewster(na,nb)    (birefringent)

Parameters

na,nb

refractive indices of left and right media

thb

Brewster angle (in degrees)

thc

critical angle of reflection or maximum angle of refraction

thcTE,thcTM

critical angle of reflection or maximum angle of refraction for TE and TM

Description

brewster(na,nb) calculates Brewster and critical angles. In birefringent (uniaxial or biaxial) case, na,nb are turned into 3-d arrays and thcTE is critical or maxiumum depending on na(2)or nb(2) is larger whereas thcTM depends on na(3) or nb(3) is larger.

Examples
