planar (version 1.6)

lfief: lfief

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

Value

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

Details

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