Polarization (Definition, Linear, Circular, Elliptical, Loss Factor, Example & Types)
Polarization of EM Waves
Definition of Polarization
• Polarization is the Orientation of the Electric Field.
Linear Polarization
• In Linear Polarization, the orientation of the Electric field is there in a single Axis.
Circular Polarization
• In Circular Polarization, E Field rotates circularly with respect to time.
• In Circular Polarization, the Magnitude of the E field is equal on the x and y-axis.
• CW Circular Polarization is also known as Right Hand Circular Polarization.
• CCW Circular Polarization is also known as Left Hand Circular Polarization.
Elliptical Polarization
• In Elliptical Polarization, E Field rotates circularly with respect to time.
• In Elliptical Polarization, the Magnitude of the E field is not equal on the x and y-axis.
• CW Elliptical Polarization is also known as Right Hand Elliptical Polarization.
• CCW Elliptical Polarization is also known as Left Hand Elliptical Polarization.
Polarization Loss Factor
Co-Polarization and Cross-Polarization
• Polarization in the Desired direction is Co-polarization.
• Polarization orthogonal to Co-polarization is Cross-polarization.
