The propagation of electromagnetic waves is detected in semiconductive Bi 1−x Sb x alloys in a direction perpendicular to the magnetic field at helium temperatures and in a frequency range between 36 and 140 GHz. For lacking spatial dispersion and for arbitrary orientations of the magnetic field the wave propagation takes place within the trigonal plane. In both, the quasiclassical limiting case and the ultra‐quantum state, it is found that the experimentally and theoretically determined values of wave dispersion are in mutual agreement. The measurements permit statements to be made about the cyclotron masses and it is possible to obtain a spin splitting parameter of G 2 = 0.9.
