The Method of Substationary Point SearchIn practical terms, electromagnetic (EM) waves in materials of limited dimensions correspond to those in systems such as coaxial cables, optical fibers, and wave guides. It is by this process that signals, and therefore information, are transmitted with as low a degree of attenuation and parasitic phenomena as possible.

Introduction to the Fundamental Equations of Electrostatics and Magnetostatics in vacuums and ConduA gradient is the vectorial magnitude of a scalar. For example, the scalar (Ф) which at point P has coordinates x,y,z, takes on a value Ф(x,y,z). By definition, at the point P (see Figure 1.1), the gradient of Ф is given by a vectorial magnitude, as in: . Ф(x,y,z), which is such that .

Electrostatics of Dielectric Materials,A dielectric is effectively an insulator, meaning that . it does not have free and mobile charges. Nevertheless, different types of charges can be found, as shown in Figure 2.1. They are:

Waves in Plasmas and Dielectric, Metallic, and Magnetic Materials,So that geometrical considerations do not become a problem, this chapter will look at the interactions of electromagnetic (EM) waves with materials that have infinite dimensions. Materials with limited forms will be looked at, most notably, in Chapters 11 and 12.

Interactions between Materials and Electromagnetic Waves, and Diffusion and Absorption Processes,Having looked at the way in which electromagnetic (EM) waves are emitted by a particle accelerating in a vacuum in Chapter 9, this chapter is concerned with how EM waves interact with materials, and in particular:
