    • Abstract

       

      The natural optical selectivity of a material exhibited in the form of its reflectance, transmittance, or emittance spectra can be modified and tailored to yield any desired profile by applying surface coatings in the form of multilayers of suitable materials, or composite materials having an appropriate graded composition. This paper reviews the modes of selectivity, design and modelling of some technologically important optically selective coatings.
