If a right-handed circularly polarized wave is incident normally on a plane perfect conductor, then the reflected wave will be

(A) right-handed circularly polarized
(B) left-handed circularly polarized
(C) elliptically polarized with a tilt angle of 45°
(D) horizontally polarized

Correct answer: (B) left-handed circularly polarized

Solution

When a right-handed circularly polarized wave reflects off a perfect conductor, the phase of the electric field component reverses, resulting in a left-handed circularly polarized wave.

The diodes D1 and D2 in the figure are ideal and the capacitors are identical. The product RC is very large compared to the time period of the ac voltage. Assuming that the diodes do not breakdown in the reverse bias, the output voltage V0 (in volt) at the steady state is ----------- The ac source is 10 sin ωt, connected between the left node and the midpoint of two identical capacitors C connected in series between the top and bottom rails. Ideal diode D1 is on the top rail from left to right, ideal diode D2 is on the bottom rail from left to right, and the load resistor R is connected between the top and bottom rails with V0 measured across R, positive at the top rail and negative at the bottom rail.
