Electromagnetic waves are formed when an electric field (E-field) couples with a magnetic field (H-field). Field vectors of the electric and the magnetic field of an electromagnetic wave are perpendicular to each other and to the direction of the wave (Fig. 4.1). The plane containing the field vectors of the E-field defines the polarization of the wave (linear, circular, or elliptical).
