“…Quantities accessible to experimental measurement are then I Y I , +r and A given above. Direct measurements of the latter quantity A are particularly common in microwave reflection experiments involving semimetals and semiconductors of high conductivity , Nii 1964, Bermon 1967, Perkowitz 1969). ,4s is often done in the case of highly conducting media, reflection features can alternatively be described in terms of the complex surface impedance 2.…”

“…I n the limit 6<Rc, the well-known AKCR arises (see, for example, Lax and Mavroides 1960). I n semiconductors this inequality is not satisfied when W ~T > 1, but even the relatively small spatial variation of the field intensity across the cyclotron orbit is sufficient to excite weak AKCR (Suzuki et al 1961, Perkowitz 1969. The physical basis for the existence of resonance at w = wc in the EV geometry is that the longitudinal fields, because of their spatial variation, are insufficient to screen out the circularly polarized internal CRA field completely, and some resonant coupling is possible.…”

“…Similarly, in the OV geometry, nonlocal conditions predict AKCR fundamental absorption as well as a series of weak subharmonics (Suzuki et al 1961, Hebel 1965, Perkowitz 1969, in contrast to the local theory, which leads to completely field-independent response for isotropic bands. An intuitive picture for the appearance of resonance in this configuration, as well as for the subharmonics in the EV geometry, is elusive under conditions of weak nonlocality, except by bold appeal to the phase-matching argument which so graphically describes AKCR when 6 < R,.…”

The magnetic-field-dependent microwave absorption is measured in semiconducting Bil -,Sb, alloys in the frequency ranges of 36 and 70 GHz a t helium temperatures. I n addition to cyclotron resonance, tilted orbit resonance ist observed. A theoretical lineshape analysis is carried out. The comparison with the experiment shows good agreement. Moreover the hybrid resonance and the dielectric anomaly are discussed and their influence on the magnetic-field-dependent microwave absorption in the present material is investigated. The results can in effect be understood on the basis of a model of the isoenergy surface, which is composed of three ellipsoidal parts. Moreover there are indications of deviation from this model.
