Here we present the dependences of the phase and attenuation constants of silicon carbide (SiC) cylindrical rod waveguide upon frequency at different temperatures, i.e. T = 1800C and T = 1900C when the rod radius is relatively large. We have also calculated the electric and magnetic field distributions at different frequencies in order to explain the anomalous attenuation. The SiC rod waveguide was investigated by the partial area method. The complex roots have been found by the Müller method. Computer codes for calculations were written in MATLAB language.
