Thermoviscoelastic surface waves of an assigned wavelength

Massively Sub-wavelength Guiding of Electromagnetic Waves

Recently a new form of ultra-thin flexible waveguide consisting of a conducting comb-like structure with a thickness of the order of 1/600(th) of the operating wavelength was presented. However, whilst the thickness of the guide was massively sub-wavelength, the remaining dimensions (the height and period of the comb) were much longer. In this paper we propose, and experimentally verify, that a...

Observations of Sea Surface Waves in Wide Wavelength Range with Optical System

This paper is concerned with the real-time observation system of optical devices for recording of sea waves characteristics in wide range of wavelength from centimeters to hundreds meter. The energy spectra of short waves are obtained in real time by spectral analysis of sea surface image [1] with spectral analyzer operating under no coherent light. The spectral-kinematics characteristics of lo...

Wave Processes in Thermoviscoelastic Medium

A thermoviscoelastic body model is formulated, that comprises the nonlinear hyperbolic heat conductivity equation. A dependence of the thermal flux relaxation time on the magnitude of heat flux and temperature has been built. The examples of solving particular problems are given. The calculation results are compared to the experimenlal ones.

A Theory of Thermoviscoelastic Dielectrics

Scattering of Surface Waves

In this chapter the theory of scattering of elastic surface waves is described. Since surface waves are guided along the surface of materials, the scattering properties of surface waves are useful for probing the heterogeneity of the material near the surface as well as perturbations of the free surface. This has applications in the detection of surface defects (Steg and Klemens, 1974) and in s...
