Abstract :
Herein, we present the field/stress tunable features of microwave behaviour of epoxy-based composites containing CCMA-ed Co-based microwires of different lengths so as to look into the effects of the CCMA. A decrease-increase trend of permittivity (ε) spectra is revealed in the CCMA-ed wires composites in presence of magnetic fields. A linear positive stress-ε dependency is shown in the composite containing 25 mm CCMA-ed wires.
