Q.

A circular cavity resonator has a wave number of 151, radius of 2.74 cm, and surface resistance of 0.0184Ω. If the cavity is filled with a dielectric of 2.01, then unloaded Q due to conductor loss is:

A. 25490
B. 21460
C. 29390
D. none of the mentioned
Answer» C. 29390
Explanation: unloaded q of a circular resonator due to conductor loss is given by ka/2rs. is the intrinsic impedance of the medium. substituting the given values in the equation for loaded q, value is 29390.
