recursive_fresnel: recursive_fresnel

Description

Multilayer Fresnel coefficients

Usage

recursive_fresnel(wavelength = 2 * pi/k0, k0 = 2 * pi/wavelength, angle = NULL, q = sin(angle), epsilon = list(incident = 1.5^2, 1.33^2), thickness = c(0, 0), polarisation = c("p", "s"))

Arguments

angle

[vector] incident angles in radians

q

[vector] normalised incident in-plane wavevector

epsilon

list of N+2 dielectric functions, each of length 1 or length(wavelength)

thickness

vector of N+2 layer thicknesses, first and last are dummy

polarisation

[character] switch between p- and s- polarisation

Value

fresnel coefficients and field profiles
