Many problems of rundamental and. applied. physics lie in the field. of researches connected with IR—rad.iations propagation and. interaction in matter. It is common in these researches to deal with use or multilayer interrerence dielectric structures ror solution of some problems of clarifying, riltering, splitting etc. Related long wave character or IR range and existance in it of a limited number or dielectric materials with low absorption, however, lead to some dirriculties, sometimes unavoidable, ror successrul solution or problems or design or IR optics systems. In this report optical and. spectral properties or a new class or layer—nonunirorm media (so—called superrine stratified structures (555)) are presented. They allow to avoid some problems in creating IR optics systems.
