Maxwell’s Equations

Abstract

Maxwell’s equations consist of four first-order partial differential equations . First we deal with basic properties of Maxwell’s equations. Next we show how equations of electromagnetic wave motion are derived from Maxwell’s equations along vector analysis . It is important to realize that the generation of the electromagnetic wave is a direct consequence of the interplay between the electric field and magnetic field that both change with time. We deal with behaviors of electromagnetic waves in dielectric media where no true charge exists. At a first glance, this restriction seems to narrow a range of application of principles of electromagnetism . In practice, however, such a situation is universalistic; topics cover a wide range of electromagnetic phenomena, e.g., light propagation in dielectrics including water, glass , polymers. Polarized properties characterize the electromagnetic waves. These include linear, circular, and elliptic polarizations . The characteristics are important both from a fundamental aspect and from the point of view of optical applications.
