Jc. Liu et al., ACCURATE MEASUREMENT OF THE Q-FACTOR FOR THE CAVITY PERTURBATION METHOD, Microwave and optical technology letters, 13(2), 1996, pp. 87-90
The sensitivity of cavity Q-factor measurements in the cavity perturba
tion method can be improved by using the differential averaging techni
que. The complex permittivity of low-loss dielectric samples are accur
ately obtained by evaluating the differential averaging values among t
he original and perturbed frequency responses. (C) 1996 John Wiley & S
