Microwave Characterization of Silicon Carbide Sample at …

This article presents a microwave characterization at the ISM band (2.45 GHz) for the dielectric properties of a Silicon Carbide sample with high loss tangent from 25 C to 165 C. Different techniques were used to characterize the SiC sample: the cylindrical resonant cavity technique in transmission and reflection mode, the microstrip ring resonator and finally the near field microwave microscopy.
