Polarization Waves | PDF | Polarization (Waves) | Waves Polarization describes the orientation of the electric field of an electromagnetic wave. it can be linear, circular, or elliptical. the polarization of an antenna is defined as the polarization of the wave it radiates in the direction of maximum gain. Suppose we have a plane wave moving in the zˆ direction whose electric field is polarized in the xˆ yˆ direction. say this wave passes through a calcite crystal of thickness l whose optical axes are aligned with the xˆ and yˆ directions.

Polarization. | PDF After traversing a quarter wave plate aligned with its crystal axes parallel to xˆ and yˆ , a net phase shift of 90o will occur so that the wave can now be represented by:. Two parallel coherent linearly polarized waves will interfere in the same way as natural light. the two constituent orthogonal linearly polarized states of natural light cannot interfere to form a readily observable interference pattern, even if rotated into alignment (because they are incoherent). These effects do not tell us about the type of wave motion that is whether the light waves are longitudinal or transverse or whether the vibrations are linear or circular. the phenomenon of polarization has helped to establish beyond doubt that light waves are transverse. A polarizer allows waves polarized in a particular direction to pass but absorbs waves polarized in the perpendicular direction. the direction that wave can pass is called the easy axis of the polarizer.

A polarizer allows waves polarized in a particular direction to pass but absorbs waves polarized in the perpendicular direction. the direction that wave can pass is called the easy axis of the polarizer. Polarization the electromagnetic wave shown above is said to be vertically polarized— meaning the direction of the electric field vector is vertical. a wave like this with the electric field vector at an angle θ to the vertical can be represented as a sum of a vertically polarized wave of amplitude ecosθ and. Along similar lines, propagation of a wave introduces potential changes to its polarization which will in turn a ect communication system performance. hence, it is important to understand how waves are polarized and the di erent polarization classi cations. It is important to reemphasize that the goal of this book is to provide a thorough understanding of the basic principles of wave polarization, antenna polarization, and the efects of the propagation medium on polarization in systems. Circular (phase= 90°) and linear polarization (phase= 0°) are special cases. their relative amplitudes will determine the orientation of the actual field vector.
