Experiments on the transmission of circularly polarized electromagnetic waves through non‐degenerate n‐type germanium in a magnetic field has been made in order to compare to a theoretical dispersion relation given in part I of this paper. The experimental frequency was 45 GHz and liquid helium temperatures has been used. The dispersion relation is found to explain the experimental results very well, and by comparison between theoretical and experimental data information about the transverse and longitudinal effective mass, the lattice dielectric constant, the electron density and the relaxation time has been obtained.
