ABSTRACT

This chapter applies Maxwell’s equations to obtain electromagnetic (EM) wave equations, where waves are means of transporting energy or information. Typical examples of EM waves are radio waves, TV signals, radar beams and light rays. Electric and magnetic fields form an EM wave that has no electric or magnetic field components along the direction of propagation, such a wave is called a transverse electromagnetic (TEM) wave and such a wave with same magnitude throughout any transverse plane is also called Uniform plane wave. The direction in which the electric field points is the polarization of a TEM wave. This chapter provides a discussion on EM wave propagation through Lossy dielectric medium. The word polarization is a manner in which the variation of magnitude and direction of the EM wave is observed. The chapter discusses three different types of polarized waves, namely, linearly polarized wave, circularly polarized wave and elliptically polarized wave.
