Elastic surface waves, or Rayleigh waves, are disturbances that travel over the stress-free surface of an elastic solid, and whose amplitudes decay rapidly with depth into the solid.

The propagation of strongly chirped pulses in an amplified fiber-optic communications system is experimentally investigated. Spectral narrowing of the pulses is observed.

The invention of the laser has revived interest in light as a communications carrier.

The first section of this paper is devoted to the formal mathematical theory of the propagation of periodic currents over a system of parallel wires energized at its physical terminals only.

A small-signal theory for the space-charge waves is derived which is in agreement with the Llewellyn-Peterson analysis for infinite beams.

Propagation of TE0i Waves in Curved Wave Guides By W. J. ALBERSHEIM TEoi waves transmitted through curve wave guides lose power by conversion to other modes, especially to T M n .

The propagation of simple walls in liquid crystals and the propagation of domain walls in magnetic chains can both be modelled by the Sine-Gordon equation with damping.

Performance of long range terrestrial wireless communication is critically affected by terrain variation.

Prediction of radio signal strength for signals propagating over valley to a mobile receiver in terrestrial clutter, such as trees and buildings, is addressed.

Propagation of radio signals from a base above clutter, such as buildings and trees to a mobile immersed in clutter, is treated theoretically by accounting for random diffuse scattering at the mobi
