Polarized by Microwaves 1. Set up the microwave source and detector system as illustrated. Align the horns in the same orienta- tion. Insert a polarizer (a rectangular grid) between the source and detector. Which orientation of the grid allows the most microwave light to pass? Which orientation will allow the least microwave light to pass? If the grid is parallel to the light, it will allow the most light to pass. A perpendicular as sd will allow the least light. 2. Consider the electrons in the metal of the grid. a. Which direction of polarization will transfer more kinetic energy to these electrons? www.w b. Determine the orientation of the polarizer that allows the minimum amount of microwave light to pass through to the detector; this will define the condition of maximum light absorption (for simplicity, we will ignore the reflection of microwaves from the metal plate). c. Determine the orientation of the polarizer that allows the maximum amount of microwave light to pass through to the detector; this will define the condition of maximum light transmission. d. Explain what happens to these vectors in the sketch below as they pass through these "smaller" slits. Draw them after they pass through the slits DATES I! IN NI! 3. From your observations above, explain whether or not the microwave source is unpolarized, par- tially polarized, or fully polarized (and if so, in which direction is it polarized?). Remove the polar- izer and rotate one horn. Does this experiment confirm or disprove your answer?
