What is cross-polarization?
AnswerIn RF communications, there are basically 3 common polarizations. They are horizontal polarization, vertical polarization, and circular polarization. Use the link below on antenna theory and see some examples and gather more information.Basically, polarization describes how the E-field is moving when it leaves the antenna.In horizontal polarization the signal moves in a horizontal fashion (-).In vertical polarization the signal moves in a vertical fashion (|).In circular polarization the signal moves in a circular fashion (O) with either left-handed or right-handed rotation.Now, when you want to talk to someone using horizontal or vertical polarization you want to match their angle of polarization exactly for the strongest signal.Cross-polarization is radiation orthogonal to the desired polarization. For instance, the cross-polarization of a vertically polarized antenna is the horizontally polarized fields.This is important to know because when you are setting up something like a satellite connection. In order to allow more signals through the satellite transponder within a fixed bandwidth and with decreased interference, the satellite makers alternate the polarization between adjacent transponder channels. (-|-|-|-|-|-|). Two adjacent channels can be "shoved right up against each other" and will interfere in a minimal way if they are polarized oppositely. Since interference affects their customers, satellite vendors are very touchy about proper polarization, and monitor gaps, called "guard bands" to ensure that you are properly aligned.

What is the geometrical meaning of cross product?
The cross product can be said to be a measure of the 'perpendicularity' of the vectors in the product. Please see the link.
How do you calculate cross sectional area for steel bars?
Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.
How do you measure volume of prisms?
Assuming the cross-section of the prism is such that its area is easily calculated, Volume of prism = Cross-sectional area * length If not, the most effective way is to submerge it in water and measure the volume of water displaced.
What is Xpic?
Cross Polarization Interference Cancellation
Polarization is a measure of?
Polarization curve is measuring the corrosion rate of the metal with respect to current and voltage.
What is cross polarization isolation?
Cross polarisation isolation or Cross Polarisation Discrinimation (XPD) is the difference in dB of received signal level (RSL) at the receiver when in turn, the transmitter has the same and different polarisation with the receiver. A antenna with this greater value is prefered. This information is useful in microwace design when in the same area we can use the same frequency with different polarisation . For example: TX1 : vertical polarisation ---> RX1 : Vertical pol. TX2 : horizontal pol. ---> RX2 : horizontal pol. They all operate in the same frequency. The signal from TX1 , TX2 will be separated corresponding to the value of XPD.
The noise jammer is inverse gain or cross eye or cross polarization or barrage jamming?

What is the most important use for a spectroscope?
a spectroscope is used to measure light waves. It can measure lights intensity, wavelength, and it polarization.

What are the types of polarization?
electronic polarization ionic or atomic polarization orientation or dipole polarization space charge polarization
Longitudinal wave do not exhibit in polarization or diffraction?
Longitudinal waves doesn't exhibit polarization or diffraction; these to features are for transverse waves.
What is activation polarization?
activation polarization is a polarization due to charge transfer kinetics of the electrochemical process involved.
Polarization is a property of?
Polarization is a property of transverse waves.
What is concentration polarization cross flow filtration?
Convective and back-diffusive flow of solvent can cause a build-up of dissolved solutes and macromolecules near and on the surface of the membrane this is known as concentration polarization. When concentration polarization occurs there is a differential solute concentration between the membrane surface and the bulk of the feed stream. The osmotic pressure in the polarized layer due to the high local solute concentration lowers the transmembrane pressure therefore decreasing flux. In cross -flow filtration there is a general decline in flux over time of operation this is due to concentration polarization. The decline in flux can be restored with the manipulation of the operating parameters.
What is polarization in the electrocardiogram?
