The effects of transverse static magnetic field on microwave absorption properties of some TPNR composites [thermoplastic natural rubber]

In this paper, we report the microwave dielectric, magnetic and absorption properties of some composites containing polypropylene (PP), natural rubber (NR), magnetite (Fe/sub 3/O/sub 4/) and yttrium iron garnet (YIG). The effects of incorporating Fe/sub 3/O/sub 4/ and YIG into the matrix of the TPNR (PP/NR) on the absorption characteristics of the material with and without the presence of a 1 T external transverse magnetic field are examined and discussed.
