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.
