lfief: lfief

In plasmonics/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)
