Description

Multilayer Fresnel coefficients

Usage

multilayer(
  wavelength = 2 * pi/k0,
  k0 = 2 * pi/wavelength,
  angle = asin(q),
  q = sin(angle),
  epsilon = list(incident = 1.5^2, 1.33),
  thickness = c(0, 0),
  polarisation = c("p", "s"),
  d = 1,
  dout = d,
  ...
)

Arguments

wavelength	[vector] wavelength in nm
k0	[vector] wavevector in nm^-1
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
d	vector of distances where LFIEF are evaluated from each interface
dout	vector of distances where LFIEF are evaluated outside the stack
