Abstract
A frequency-selective electromagnetic wave shielding material is used for shielding areas or devices from electromagnetic waves. The electromagnetic wave shielding material has a substrate with a plurality of electroconductive loop parts which are spatially allocated on the substrate, wherein each of the electroconductive loop parts is insulated from all other electroconductive loop parts.
Claims21
A frequency-selective electromagnetic wave shielding material, comprising:
- a substrate;
- a plurality of adjacent electroconductive loop parts being spatially allocated on said substrate;
- and
- each of said plurality of adjacent electroconductive loop parts being insulated from all others of said plurality of adjacent electroconductive loop parts.
A frequency-selective electromagnetic wave shielding material, comprising:
- first and second substrates;
- a plurality of adjacent electroconductive loop parts being spaced at a predetermined distance and allocated on said first substrate;
- a plurality of adjacent electroconductive loop parts being spaced at said predetermined distance and allocated on said second substrate;
- each of said plurality of adjacent electroconductive loop parts being insulated from all others of said plurality of adjacent electroconductive loop parts;
- and
- said first substrate being placed adjacent to said second substrate such that said plurality of electroconductive loop parts allocated on said first substrate and said plurality of electroconductive loop parts allocated on said second substrate appear to form an overlapping pattern when observed from a direction perpendicular to said first and second substrates.
A method for frequency-selective electromagnetic wave shielding, comprising:
- applying to at least one of a wall or window, a frequency-selective electromagnetic wave shielding material comprising a substrate, a plurality of adjacent electroconductive loop parts being spatially allocated on said substrate, and each of said plurality of adjacent electroconductive loop parts being insulated from all others of said plurality of adjacent electroconductive loop parts.
