In previous chapters we have studied the fundamental laws of electromag-netism and some of their most important applications in free space. With this, we have developed the appropriate tools to deal with the analysis of electromagnetic phenomena in material media.

To describe electrical polarization simply, at the atomic level, and show how this leads to dielectric behaviour. To define the behaviour of E and D in dielectrics and introduce the polarization vector P. To introduce piezoelectricity and electrets.

Temperature fields in swelling materials
Journal of Engineering Physics, 1983A method is outlined for calculating the nonsteady temperature fields in polymer materials swelling on heating and passing through a plastic state in the region of thermal decomposition.

Deformation of materials is carried out at room temperature and at elevated tempe-ratures. At elevated temperatures, recovery and recrystallization take place, and the flow curves depend strongly on such material parameters as temperature or strain rate.

So far, electromagnetism has been developed only for vacuum conditions. Electric and magnetic fields have corresponded to well defined distributions of electric charge and current, in otherwise empty space. The present chapter shows how field equations can be developed to take account of the presence of materials of various kinds.

High-field transport in model materials
Physical Review B, 1996The paper theoretically investigates high-field transport in the class of model materials of the nonparabolic, nonspherical energy-momentum dispersion relation ${\mathit{p}}_{\mathit{x}}^{2}$/2${\mathit{m}}_{\mathit{x}}$+${\mathit{p}}_{\mathit{y}}^{2}$/2${\mathit{m}}_{\mathit{y}}$+${\mathit{p}}_{\mathit{z}}^{2}$/2${\mathit{m}}_{\mathit{z}}$=\ensuremath{

Electromagnetic fields in material media
2023Abstract In this chapter we begin our study of electromagnetic fields in materials. We first show how the fundamental Maxwell equations give rise to ‘smoothed’ Maxwell equations valid at macroscopic scales. To use these equations, however, we must have a model for the macroscopic charge and current densities.

HRR fields for damaged materials
International Journal of Fracture, 1992The paper presents an investigation of the interaction between a macroscopic crack and distributed damage in an elastic-plastic material based on the HRR field model for virgin materials. This is achieved by describing the mechanical effects of the distributed micro-cracks in terms of the damage variable D on the HRR fields.

Materials for field emission displays
International Materials Reviews, 2001The design, development, and manufacture of field emission displays present the materials scientist with a myriad of issues and constraints. These range from the suitability of the cold cathode layer, the compatibility and adhesion of the various layers that form the device, and the overall approach to sealing and operating the display in a product ...
