The transverse magnetic reflectivity minimum of metals
journal contribution
posted on 2023-05-18, 15:45 authored by Hooper, IR, Sambles, JR, Andrew BassomAndrew BassomMetal surfaces, which are generally regarded as excellent reflectors of electromagnetic radiation, may, at high angles of incidence, become strong absorbers for transverse magnetic radiation. This effect, often referred to as the pseudo-Brewster angle, results in a reflectivity minimum, and is most strongly evident in the microwave domain, where metals are often treated as perfect conductors. A detailed analysis of this reflectivity minimum is presented here and it is shown why, in the limit of very long wavelengths, metals close to grazing incidence have a minimum in reflectance given by (√2-1)2.
