Abstract :
The paper presents studies on the microwave properties of two types of polymer composites based on acrylic resin and polyurethane with nanosized magnetic (magnetite) and dielectric (carbon) fillers. The microwave (MW) absorption was measured at 9.4 GHz, while the dielectric and magnetic properties were investigated in the frequency range 1-18 GHz. Promising MW absorption properties were observed for nanostructured filler applications in comparison with the traditional MW absorbers.
