Polarization of Electromagnetic Waves: 5 Easy Facts
Polarization of electromagnetic waves describes the orientation of the electric field as the wave travels. For radio waves and microwaves — just as for light — the three types are linear, circular, and elliptical. Antenna polarization must match between transmitter and receiver for efficient signal transfer. This guide covers EM wave polarisation, antenna types, and why polarization matters in radio communications, satellite links, and radar.
How Does Polarization Work? 5 Easy Facts on Polarizers
How does polarization work? A polariser restricts the direction in which the electric field of a light wave can vibrate. This guide covers the physics of how polarisers work — from dichroic filters and wire-grid polarisers to circular polarisers and the manufacturing process — with simple explanations and real-world examples.
