Abstract: | On the boundaries of such an isolated porous Biot layer, the total stresses and normal relative displacement are equal to
zero. For this layer, the symmetric and antisymmetric dispersion equations are established and investigated. The wave field
consists of normal waves. In this layer, one bending wave, two plate waves, and infinitely many normal waves propagate. For
all these waves, we determine dispersion curves by analytical methods. The velocities of the bending wave and the second plate
wave for the infinite frequency are equal to the Rayleigh velocity. Bibliography: 7 titles.
