Comparative Analysis of Radio-Absorbing Coatings

Le résumé fourni par la source

The development of information technologies necessitates the solution of various problems of information security. Physical means of protecting information processed by computer objects include radio-absorbing materials. They prevent the interception of information on electromagnetic radiation and interference in power supply and grounding lines. The general requirements for radar absorbent coatings are: a high level of attenuation of the reflected signal, a wide frequency range of operation and the cost-effectiveness of the structure during its manufacture and operation. The ability of a material to absorb high-frequency radiation depends on its composition and structure. The materials are quite diverse in their design and structure, and yet there are averaged performance indicators for the most established RPM groups. However, not every material can maintain performance under harsh external application conditions. The paper develops criteria for comparing the following radio-absorbing coatings: conductive paint (Shielding coating) with water-based silver Water Based Silver Conductive Coating MG Chemicals 842WB Super Shield™; Water Based Silver Coated Copper Conductive Coating MG Chemicals 843WB Super Shield™; Water Based Nickel Conductive Coating MG Chemicals 841WB Super Shield™. Their properties and advantages were investigated, and their comparative analysis was carried out on the basis of the selected criteria.
