  • Process of making synthetic magnetodielectric with controlled off-normal TE and TM response
    Patent number: 6440244
    Abstract: A synthetic magnetodielectric composite material for absorbing electromagnetic radiation has a sheet of fabric having first and second surfaces. The fabric is formed of an insulating material. Magnetically permeable thread is disposed within the fabric. The magnetically permeable thread comprises a material having a permeability substantially greater than the permeability of free space. The fabric is impregnated with resin. The magnetically permeable thread is configured to provide predetermined permittivity and permeability within a selected frequency range, so as to provide desired absorption/transmission of electromagnetic radiation.
    Type: Grant

  • High-performance matched absorber using magnetodielectrics
    Patent number: 6337125
    Abstract: A composite electromagnetic absorber provides increased EMR absorption while being thinner and/or lighter than prior art EMR absorbers. 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.
