Abstract—We present the phase and attenuation constants of open magnetoactive p-Ge rod waveguides. Dispersion characteristics of p-Ge with two component hole charge carriers waveguide are calculated when the ratio of heavy holes’ concentration in the material is equal to 15%, and 85% of the total free carrier concentration. Our algorithm allows analyzing the very high waveguide losses. There are the degeneration and the transformation of higher hybrid modes at some heavy holes’ concentrations. The waveguide broadbandwidth can be considerably extended due to the fact that the losses of the higher modes are considerably larger in comparisons to the main mode loss at the certain heavy holes’ concentration.
