High-performance matched absorber using magnetodielectrics

DETAILED DESCRIPTION The present invention provides a means and methods to create composite electromagnetic absorbers that provide increased absorption and are thinner and/or lighter than the prior art.
To accomplish this, synthetic dielectric materials are combined with either synthetic magnetic materials or magnetically lossy materials in such a way that the permittivity and permeability of the composite material are substantially matched over the desired range of frequency.
The match in the permittivity and permeability allows the majority of the electromagnetic fields to enter the material where the electric and magnetic loss components absorb the electromagnetic energy.
