Question

A polarizer is placed between a transmitter and a receiver as shown in the figure. The

transmitter is positioned vertically meaning the EM waves emitted by it will be polarized

vertically. The polarizer is placed at the center, oriented at an angle q from the vertical. The

receiver is oriented horizontally and will only receive waves parallel to it. The transmitter is

made to emit EM waves with electric field of amplitude Eo.

A. What is the amplitude of the electric field of the EM wave after the polarizer? (Write your answer in terms of Eo and q)

C. For what angle(s) q (between 0 and 360 degrees) will the amplitude of the electric field measured by the receiver be a minimum? Maximum? (Note: You will have more than one for each)

Explanation / Answer

a.E = E0 cos q b. E = E0 sin q c. for q = 0 and 180, minimum, q = 90 and 270 maximun
