Da. Usanov et Aa. Avdeev, USE OF THE AUTODYNE DETECTION EFFECT IN GUNN OSCILLATORS FOR 2-PARAMETER MEASUREMENT OF DIELECTRICS, Russian journal of nondestructive testing, 31(4), 1995, pp. 272-275
The feasibility of using low-frequency and microwave oscillations gene
rated by a Gunn diode for two-parameter measurements of dielectrics is
examined. The schematic of such an oscillator is described. A procedu
re is described for finding the thickness and permittivity of dielectr
ics.
