Ferrite-Domen Scientific Research Institute (Russian: Научно-исследовательский институт «Феррит-Домен») is a company based in Saint Petersburg, Russia.

[1] NII Domen is well known for its ferrite materials, components, and devices, which are important elements of radioelectronic systems such as radars, radioastronomy, telecommunications, and of many others.

[2] Ferrite-Domen Scientific Research Institute produces more than 50 brands of ferrogranates, ferrospinels, hexaferrites and microwave ceramic dielectrics.

[3] The specialists of the Ferrite-Domen Scientific Research Institute have created highly effective wide-range masking radio-absorbing coatings based on nanostructured films.

Such coatings, due to the use of a nanostructured film with a thickness of 4 microns, reduce the radar visibility of ground-based equipment objects in the radio frequency and infrared wavelength ranges by 10 times.
