ABSTRACT

Q-factors of natural oscillations of partly shielded half-disk dielectric resonator have been investigated. We have obtained dependences of the electronic frequency change slope of a self-excited Gunn-diode oscillator which is stabilized by a partly shielded quasi-optical resonator. There is a correlation between changes in frequency of autogeneration and a slope of electronic retiming with increment of the real and imaginary parts of permittivity of a substance.
