gaussian_near_field_layer

Electric field from the transmission of a gaussian beam at a planar interface

gaussian_near_field_layer(xyz, wavelength = 500, alpha = 15 * pi/180,
  psi = 0, w0 = 10000, epsilon = c(1.5^2, epsAg(wavelength)$epsilon, 1^2),
  thickness = c(0, 50, 0), maxEval = 3000, reqAbsError = 0, tol = 1e-04,
  progress = FALSE, field = FALSE)

Arguments

xyz

position

wavelength

wavelength

alpha
