Returns the wavelength-dependent relative dielectric function of silver (Ag)
This function uses the analytical expression given in Eq. (E.1).
The exp(-i omega t) convention is assumed.
Parameters:
- lambda: scalar, vector, or matrix
wavelengths in NANOMETERS (nm)
Returns:
- epsAg: same size as lambda
epsilon(lambda) as a complex number.
