1 (16) 2017 Резистивные, магнитные и диэлектрические свойства порошкообразных материалов различной природы позволяют использовать их при создании экранов электромагнитного излучения (ЭМИ). Известны конструкции экранов ЭМИ, отличающиеся методикой формирования экранирующих элементов конструкции на основе порошкообразных материалов: методом трафаретно...

The results of the study composite materials for electromagnetic radiation shields based on exfoliated vermiculite are described. Shielding characteristics of formed designs based on composite materials in the frequency range 0,7…17 HHz are obtained.

A wide utilization of electronic equipment produces the need in integration of building and shielding technologies. This would allow to construct premises and buildings, capable of attenuation of the electromagnetic fields, generated by industrious and household sources. Such kinds of premises would solve the problems of electromagnetic compatibili...

The developed multilayered shielding structure involves materials with magnetic and dielectric losses. The frequency dependence of the reflection coefficient and the attenuation of the EMR in the range of 8.0⋯ 12.0 GHz are studied.

Frequency dependences of shielding characteristic of samples of designs on the basis of composites with organic hydrophilic components in the range (8...12) GHz are presented. It is shown that composites on the basis of moisture containing wood shaving lead to electromagnetic wave weakening of about 20 dB with possibility of going up to higher than...

Polymerous water-containing material based on the cross-linked polymerous hydrogel soaked in inorganic salt and put into the container made of polyamide films is designed. Frequency dependence on the reflectance coefficient of EMR is obtained in the range of 8.0...12.0 GHz at temperature range from minus 15 to plus 50°C.

We offer the composite liquid-containing material based on the capillary-porous matrixes impregnated with a hygroscopic inorganic salt solution and with two sides covered with crystalline water-retentive polymer layers. Time behavior of composite materials surface temperature is obtained. Dependence of IR-radiation shielding efficiency on compositi...

Composite shielding materials based on capillary-porous matrixes impregnated with liquid solutions possessing resistive and dielectric losses for microwave electromagnetic radiation (EMR) are developed. Meeting the objectives the EMR attenuation obtained by the proposed materials can be higher than 40 dB, with the reflection level lower than -10 dB...
