Abstract: It was found experimentally that a resonant periodic profile on the surface of polycrystalline BeO produced a gap of 30 cm^{– 1} width in the dispersion curve of surface polaritons in the region of 930 cm^– 1. This made it possible to control the infrared reflection spectra of optically rough BeO in the region of the emission frequency of a CO₂ laser.
