Distributed Reflection of Light,

Abstract

The author has recently discovered a method for reducing the wave equation to quadratures and can give the exact analytic continuation from the WKB regime (slowly varying index of refraction) to the interface extreme (discontinuous index). There was noticed a very special impedance matching strategy (anti-reflective coating) that is far better than the universally used 'quarter wavelength coating'. The coating is not wavelength dependent. The impedance matching profile is called the magic slide because of the way is slips a beam into the bulk medium of an optical element. The magic slide is the unique profile of a spatially varying index of refraction that produces no distributed feedback (distributed reflection) whatsoever. Thus the wave slides free from interface to interface. (Modified author abstract)
