Hi i am trying to understand what is polarization and why do we need it? We use the term of polarization in university in a wireless communications course.. Plz i need some articles to study..
Thx a lot
Thx a lot
There is no difference between the two polarizations except the polarization is 90 degrees apart. If you line up your antenna to receive one signal at its maximum power, you'll receive none of the other polarization.dervast said:Hmm in a wireless course in university teacher used the terms of horizontal and vertical polarization of a signal.. When do we use horizontal and when do we use vertical polarization .. What the main difference between them?
I think you mean to say both E and M oscilate pepindicular to direction of propagation here.woodsy2k said:These oscilate about an axis that is parallel to the direction of propagation, and they oscilate at 90 degrees to each other.
Polarization is a phenomenon that occurs when light waves vibrate in a single plane instead of in all directions. This can happen when light reflects off a smooth surface, passes through certain materials, or is created by special filters.
Polarization is important in many areas of science and technology. It allows us to control the amount and direction of light that passes through a material, which is useful in fields such as photography, optical communication, and microscopy.
The human eye is sensitive to polarized light, and polarization plays a role in how we perceive and see the world around us. For example, polarized sunglasses can reduce glare and improve visual clarity by filtering out horizontal light waves.
Polarization can be reversed by passing light through a polarizing filter in the opposite orientation. This is useful in applications where control of the polarization of light is necessary, such as in LCD displays or 3D glasses.
Yes, there are natural sources of polarized light, such as sunlight that reflects off of water or other smooth surfaces, or light that passes through certain minerals or crystals. Animals like bees and insects also use polarized light for navigation and communication.
