Bq. Tian et Wr. Tinga, LINEARITY CONDITION BETWEEN A CAVITYS Q-FACTOR AND ITS INPUT RESONANTRESISTANCE, IEEE transactions on microwave theory and techniques, 43(3), 1995, pp. 691-692
This paper proves that a linear relationship between a cavity's Q-fact
or and its input resonant resistance holds rigorously true provided th
e Q variation is caused only by power loss in the cavity.
