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).

The image represents Transmission spectra of mylar films with nanostructured AlN layers in 2-25 µm IR spectral range (click to view full-size).

Development created in collaboration with Institute for Metal Physics of NASU.
