METHODS AND COMPOSITIONS FOR DESTRUCTIVE INTERFERENCE

摘要

A composition for destructive interference in at least a portion of the frequency range from 1 GHz to 20 GHz can comprise a dielectric and a conductive filler mixed with at least a portion of the dielectric, wherein the percentage volume of the conductive filler relative to the total volume of the composition is configured such that the wavelength of sensitivity for the composition is on the order of a wavelength of an incident electromagnetic radiation in at least a portion of the frequency range from 1 GHz to 20 GHz.
