Nonlinear Theory of Acoustoelectronic Waves in Semiconductors, of harmonics, are also considered. The specific features of acoustoelectronic interactions for surface acoustic waves are pointed out. A comparison of the theory of acoustoelectronic interactions with the experimental data is briefly given.明确 发表于 2025-3-23 15:36:51
Nonlinear Waves in Ferromagnetic Films,s have permeabilities close to unity but the transition elements give rise to substantial values. In paramagnetic materials, however, the magnetic ions are practically independent of each other. The orientation of the magnetic moments of these ions is chaotic, with the average moment of the whole volume being equal to zero.canvass 发表于 2025-3-23 20:08:37

Surface Acoustic Waves on Nonlinear Substrates, that involve no change in the frequency of the wave. In addition, in the calculations described in this chapter we will confine ourselves primarily to non-piezoelectric materials. However, their extension to piezoelectric media will be indicated briefly.茁壮成长 发表于 2025-3-24 23:43:35
