drude: drude

In dielectric: Defines some physical constants and dielectric functions commonly used in optics, plasmonics.

Description

Drude model for the dielectric function of good (governed by free electrons) metals

Usage

  drude(wavelength = 633, p = c(1e+16, 1e+14, 1),
    omega = 2 * pi * 1e+09 * 299792458/wavelength,
    omega_p = p[1], gamma_p = p[2], epsilon_inf = p[3],
    ...)

Arguments

wavelength	wavelength in nm
p	vector of 3 parameters
omega	angular frequency in rad/s
omega_p	plasma frequency in rad/s
gamma_p	damping constant, in rad/s
epsilon_inf	background dielectric function
...	not used

Details

a bacground contribution eps_inf is assumed for the core electrons

Value

a data.frame with wavelength in nm and complex dielectric function
