epsDrude

PURPOSE ^

Returns the wavelength-dependent relative dielectric function of a Drude metal

SYNOPSIS ^

function epsDrude = epsDrude(lambda,eps_infty,lambda_p,mu_p)

DESCRIPTION ^

 Returns the wavelength-dependent relative dielectric function of a Drude metal
 The analytical expression is given in Eq. (3.2).
 The exp(-i omega t) convention is assumed.

 Parameters:
 - lambda: scalar, vector, or matrix
           wavelengths in NANOMETERS (nm).
 - eps_infty: scalar
              eps_infty (see Eq. 3.2). 
 - lambda_p: scalar
             wavelength in NANOMETERS (nm) corresponding to
             plasma frequency omega_p [rad/s]: lambda_p=2*pi*c/(omega_p)
 - mu_p: scalar
         wavelength in NANOMETERS (nm) corresponding to
         damping term gamma_0 [rad/s]: mu_p=2*pi*c/(gamma_0)
 
 Returns:
 - epsDrude: same size as lambda
          epsilon(lambda) as a complex number.
