Shielding characteristics of fiber organic water-containing materials under exposure of elevated temperature

The frequency dependence of the attenuation and reflection of electromagnetic radiation of wet fibrous materials based on organic structures in the range of 8 – 12 GHz has been investigated. The possibility of extending the temperature range of operation of the testmaterials to 180 °C withminimal loss of the liquid component andmaintaining high shielding performance was considered. Practical recommendations for the creation of shielding structures to protect objects fromstray electromagnetic radiation are proposed.
