Description Calculate surface emissivity of a specular surface.
Arguments and Return Values Arguments: The real and imaginary optical constants (single value or vectors) and an emission angle. Return Value: An output value or spectrum.
Usage Syntax: fresnel(real_index, imaginary_index, emission) real_index: array containing the real indices of refraction imaginary_index: array containing imaginary indices of refraction emission: viewing emission angle (degrees)
