FIELD: heating.
SUBSTANCE: invention relates to heat engineering, and namely to material, the emitting/absorbing capacity of which is close to that of an absolutely black body. Metamaterial represents periodically alternating strips of conducting material (metal) and dielectric; with that, width of dielectric strips is larger than length of emission maximum wave at the specified temperature; conducting material cross section has the shape of rectangles with a flat end face projecting onto the emitting surface, or triangles with a vertex directed towards the emitting surface and leaving it; in both cases the curvature radius between adjacent planes of the conducting material shall be less than length of emission maximum wave at the specified temperature; at the triangle cross section of the conducting material the height of triangles is larger than length of emission maximum wave at the specified temperature.
EFFECT: creation of material, the emitting/absorbing capacity of which is close to an absolutely black body.
