Omni-directional selective shielding material based on amorphous glass coated microwires

Abstract

The shielding effectiveness of the omni-directional selective shielding material based on CoFe-glass coated amorphous wires in 0.8 GHz-3 GHz microwave frequency range is investigated. The measurements were done in a controlled medium using a TEM cell and in the free space using horn antennas, respectively. Experimental results indicate that the composite shielding material can be developed with desired shielding effectiveness and selective absorption of the microwave frequency range by controlling the number of the layers and the length of microwires.

Study of the knitted structures with different designs used for electromagnetic shielding

“…) [10,11,12,13]. The shielding effectiveness measurements of the knitted structures were made introducing the structure between the two horn antennas having the same polarization direction.…”
