lfief: lfief

In planar: Multilayer Optics

Description

Local field intensity enhancement factors in a multilayer

Usage

lfief(wavelength = 500, angle = 0, polarisation = "p", thickness = c(0,
  20, 140, 20, 0), dmax = 200, res = 1000, res2 = res/10,
  epsilon = list(1^2, -12, 1.38^2, -12, 1.46^2), displacement = FALSE, ...)

Arguments

wavelength	wavelength
angle	angle
polarisation	polarisation
thickness	vector of layer thickness
dmax	maximum distance to interface, if > layer thickness
res	resolution of sampling points
res2	resolution of sampling points outside stack
epsilon	list of permittivities
displacement	logical, Mperp corresponds to displacement squared (D=epsilon x E)
...	further args passed to multilayer

Details

returns the LFIEFs as a function of distance inside and outside of the structure

Value

long format data.frame with positions and LFEF (para and perp)
