A metallic waveguide tuned to an infrared region of interest provides spectral and spatial control over emitted/absorbed thermal radiation. The ratio of the depth of the waveguide to the smallest lateral dimension thereof is such that that the lateral dimension provides spectral selectivity and that the waveguide is deep enough for a fixed lateral dimension to establish directionality but is not so deep that it incurs severe ohmic losses. A panel with an array of such waveguides directs thermal radiation from a body in a specific direction and with a spectral response that is the result of the physical dimensions of the individual waveguides that make up the waveguide array and the arrangement of the waveguides in the array. The waveguide axis may be obliquely oriented with respect to the substrate normal so as to impart non-normal directionality to the emitted radiation with respect to the substrate normal surface.
