Synthesis and characterization of magneto-dielectric composites for radio frequency applications

Abstract

Engineered materials are becoming increasingly important for radio frequency (RF) design. Some RF applications include antennas, circulators, and transmission lines - all of which are used for cell phones, cars, laptops, etc. Magneto-dielectric materials can be used for radio frequency applications and possess an engineered permittivity and permeability while still retaining a low loss. For this study, nanocomposites were cured using diglycidyl ether of bisphenol F (DGEBF) with 4,4' diamino diphenyl sulfone (DDS) as the curing agent. Nanoparticles used for this study include iron oxide (Fe 3O4) nanopowder of spherical morphology. An ultrasonication technique was used for synthesis of the composites with varying weight percent of the inclusions. Dielectric properties were analyzed as a function of both frequency and temperature. Magnetic properties were measured as a function of frequency. A sufficient dielectric constant was achieved (near 6); whereas, the magnetic permeability was still low. Future research will focus on measuring the mechanical properties of the composites to see if the material can maintain good properties while still having high concentrations of iron oxide filler. Moreover, a more detailed look at the effects on cure characteristics will be carried out. Also, different processing techniques will be used - i.e. microwave processing, compression molding, etc.
