Examination of thermal plasma data obtained by low-altitude satellite measurements shows that the low-altitude cusp represents a well-expressed plasma structure, specified with one or more boundaries at which the density (or Alfven velocity) abruptly changes. Inside the cusp the Alfven velocity variations in amplitude are smaller by an order of magnitude. These structural features are used to construct a plasma model of the cusp, and the model is used to study wave disturbances of a surface nature. The polarization state of compressional surface modes in a homogeneous plasma layer with low beta is examined. It is shown that the compressional surface MHD modes generally have elliptical polarization, the sign of which changes three times, at the interfaces and the central line. Jumps in the tangential component of the disturbance field can be used to identify compressional surface modes of discontinuities in the magnetosphere, solar winds, etc.
