The aim of this work is to discuss the possibility of resistive thin-film coatings used for vacuum electron devices. Following a short review, results on radiophysical parameters studies in millimeter-band of such coatings are presented. Resistive Sn-O coatings with varied oxygen content were fabricated on quartz substrates by reactive magnetron sputtering. Morphology and elemental composition of prepared coatings were studied by means of scanning electron microscopy and secondary ion mass spectrometry, while four-probe method was utilized to study the resistivity of those. Dielectric properties were measured in the V-band (50-70 GHz) in free space using vector network analyzer. It was demonstrated that resistivity and the dielectric properties of coating in millimeter-band can be widely varied by controlling coating composition.

Metallic mesh coatings are used on visible and infrared windows and domes widely to provide shielding from EMI (Electromagnetic Interference). In this paper, different EMI mesh geometries are compared with each other regarding various performance parameters. But to decide the best fitting EMI mesh geometry to particular optic system is a little bit complicated issue. Therefore, we try to find a simple optimization methodology to decide best EMI mesh geometry design that fits our particular high performance ISR (Intelligence, Surveillance and Reconnaissance) systems.

“…Экранирование электромагнитного излучения происходит за счет поглощения и отражения. Следует отметить, что в случае толстых пленочных структур также необходимо учитывать множественные отражения [10]. Коэффициент отражения (R), передачи (T SHF ) и поглощения (A) мощности можно выразить как [10].…”

This work shows a simple and affordable technology for producing a thin-film transparent radio-shielding material. The material is a silver micromesh coating produced using a self-organized template. The results of a study of the radio-shielding properties of the silver micromesh coatings in the X- and K-bands are presented. It is shown that a micromesh coating with a sheet resistance of 6.8 Ω/sq and an integral optical transmittance of 83.6 % is characterized by a shielding efficiency (SE) of 28.4 dB at a frequency of 8 GHz, which corresponds to a shielding of 99.85% of radiation. The main shielding mechanism for micromesh coatings is reflection of radiation.
