Hi i need to read somewhere about polarization. What polariation is.. Why we need it? What types of polarization exist and what are the differences.. and so on
Polarization is important in wireless communications. This technology comes from one that has been developed since 19th century, radio communications. When radio waves are generated, the polarity of the electric field defines the polarity of the antenna. The electric field is perpendicular (orthogonal) to the magnetic field in a linearly polarized antenna.dervast said:Thx i ll read your interesting links.. I am asking because we are using polarization in wireless communications.. and he polarization seems to be a factor that alters somehow the attributes of the signals/
Polarization is a phenomenon that occurs when light waves, or other types of waves, vibrate in a specific direction. This results in the waves being restricted to a single plane of oscillation.
Polarization causes light to behave differently, depending on its orientation. For example, polarized sunglasses are designed to block light waves that are horizontally polarized, which reduces glare and improves visibility.
Polarization can be caused by various factors, such as reflection, refraction, and scattering. When light waves interact with a surface, they can become polarized due to the orientation of the molecules in the surface.
Polarization is used in various technologies, such as LCD screens, 3D glasses, and polarizing filters. In LCD screens, polarization is used to control the amount of light that passes through the liquid crystals to create images. In 3D glasses, polarization is used to separate different images for each eye, creating a 3D effect. And in polarizing filters, polarization is used to reduce glare and improve image quality.
Yes, polarization can be reversed by passing light waves through a polarizing filter in the opposite orientation. This process is called polarization reversal or depolarization. It is used in some technologies, such as 3D movie screens, to switch between different images for each eye.
