horizontal polarization การใช้

• Now have the flashlight move to the left and right representing horizontal polarization.
• AM and FM broadcast radio usually use vertical polarization, while television uses horizontal polarization.
• However it remains a good reflector especially for horizontal polarization and grazing angles of incidence.
• For horizontal polarization, there is cancellation at that angle.
• At low frequencies especially, horizontal polarization is avoided.
• The 85 GHz horizontal polarization subsequently had a large increase in radiometric errors and was switched off in summer 1988.
• After a double pass through the amplification medium, having the same horizontal polarization, the pulse will be transmitted by the polarizer.
• Taking beam tilt into account, the station's effective radiated power is rated at 300, 000 watts horizontal polarization and 100, 000 watts vertical.
• We must express the state of vertical and horizontal polarizations as the superpositions of states of polarization at " 45?" and " 135?".
• But the photons may be entangled, so that if one is measured and has a horizontal polarization, then the other will have that polarization, too.
• The recipient can set the receiver in one of two configurations, so it can distinguish between vertical and horizontal polarizations, or between one of two diagonal polarizations.
• However, the particular results are completely random; it is impossible for Alice to predict if she ( and thus Bob ) will get vertical polarization or horizontal polarization.
• It is a wideband TV transmitter ( horizontal polarization ), though an original A group aerial will still receive the three main Public Service Broadcast ( PSB ) Muxes.
• Antennas with horizontal elements, such as most rooftop TV antennas in the United States, are horizontally polarized ( broadcast TV in the U . S . usually uses horizontal polarization ).
• Horizontal polarization turns into vertical polarization if you rotate your frame of reference, but clockwise circular stays clockwise circular when rotated, and also when you change the speed of the reference frame.
• You have a pair of glasses with horizontal polarization . . . and behind that a set of liquid crystals that polarize vertically when they are turned on-and horizontally when they are off.
• This implies, of course, that every photon has a probability of 1 / 2 to pass a test of this type exactly as it has to pass the tests for vertical and horizontal polarization.
• Analogously, suppose that the photon on the left, indicated as " 1 ", has a horizontal polarization, so that it is described by the vector state \ left | 1, H \ right \ rang.
• First, the entangled states are perfectly correlated in the sense that if Alice and Bob both measure whether their particles have vertical or horizontal polarizations, they always get the same answer with 100 % probability.
• Sea clutter can be reduced by using horizontal polarization, while rain is reduced with circular polarization ( note that meteorological radars wish for the opposite effect, and therefore use linear polarization to detect precipitation ).
