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.
