Wave Transmission, Attenuation, and Isolation. Vibrations are
transmitted through soils by stress waves. For most engineering analyses, the soil may
be treated as an ideal homogeneous, isotropic elastic material to determine the
characteristics of the stress waves.

Half-Space. Two types of body waves may be transmitted in an ideal
half-space, compression (P-) waves and shear (S-) waves; at the surface of the half-
space, a third wave known as the Rayleigh (R-) wave or surface wave will be
