✦ Synopsis

It is well known that an elastic homogeneous half-space does not allow torsional surface waves to propagate.

The present paper attempts to find out the possibility of propagation of such waves in a viscoelastic half-space. The study reveals that although the homogeneous elastic half-space does not allow torsional surface waves to propagate, a viscoelastic half-space does so. The wave is damped due to the viscoelastic parameter. It has also been found that as the viscoelastic parameter decreases, the medium becomes elastic and the torsional surface waves ceases to propagate.

The paper discusses the propagation of torsional surface wave in a homogeneous substratum over a half-space with linearly varying rigidity and density. The study reveals that under assumed conditions, a torsional surface wave propagates in the medium. The velocities of torsional surface waves have b

A discrete-time wave propagation formulation of the seismic response of tall buildings is introduced. The building is modeled as a layered medium, similar to a layered soil medium, and is subjected to vertically propagating seismic shear waves. Soil layers and the bedrock under the foundation are in

Measurements of the propagation of UHF radio wa¨es in two trapezoidal tunnels are reported. Values of propagation loss in dBr100 m are gi¨en. It is found that the propagation attenuates at least 900 MHz. In addition, a portable FM radio system operating at 900 MHz is tested in one tunnel. It achie¨e
