6H10.20 Dichroic Polarization: Microwave Polarization
Photo of the Demonstration at the University of Texas at Austin.
Instructions / Notes:
- A microwave transmitter horn is aimed at its corresponding receiver horn.
-
The receiver unit has an audio amplifier atttached to it which must also be switched on for students to hear the signal strength.
- Two sets of metal grates are provided to place in between the transmitter and receiver.
-
The transmitter warm up time is about 1 minute after being switched on.

-
When the metal grate is placed in the vertical position - as shown - it will block the signal to the receiver.

-
To show cross polarization, place the transmitter on its side, as shown above.
-
To show cross polarization, place the transmitter on its side, as shown above.
-
At 90 degrees cross polarization the signal strength at the receiver will read zero.
-
Rotate the metal grate 45 degree and an attenuated signal should be heard.
