Surface impedance boundary condition for metallic diffraction gratings in the optical and infrared range
The metallic diffraction grating problem is solved for S polarization using a conformal mapping and the surface impedance boundary condition. This completes the first differential formalism for diffraction gratings valid for good real conductors which does not require the fields inside the metal to...
