Functional selective coatings blocking radiation in the infrared and passing in the microwave spectral range

Purpose - can be used as elements of filtering devices for:

• decrease of an object detection in IR spectral range;
• assurance of high level of desired informative signal in radio-frequency (2-36 GHz) and sub-THz spectral ranges (65+-10, 140+-1, 270+-10 GHz, the losses in these spectral ranges are <= 0.06-0.2 dB (<=1.4-4.6 %) at thicknesses of nanostructured  AlN coatings ~1-3 µm);

• cryogenic receiving systems for modern navigation networks, positioning and telecommunications (for protection of the cryoelements of detecting systems from harmful thermal IR radiation and thermal shock).
