Abstract : A previously developed theory of surface polaritons is used to calculate the surface magnetoplasmon modes for materials with anisotropic energy surfaces such as the lead chalcogenides and n-type germanium. These materials are characterized by a Fermi surface consisting of prolate spheroids with axes in the (111) symmetry directions. Results are compared to the surface magnetoplasmon modes in substances having a spherical Fermi surface. Specific calculations are made for p-type PbTe with the external magnetic field parallel to the (100) and (110) directions, with the surface parallel to and perpendicular to the magnetic field. Retardation is included for the case of the magnetic field parallel to the surface and the direction of propagation normal to the field. (Author)
