Abstract :
Bragg FEM with a two-mirror resonator including advanced Bragg structure based on coupling of propagating and quasi-cutoff waves was studied. Implication of the cutoff wave into the feedback loop improves selectivity of the Bragg resonators over transverse coordinates and allows advance of FEM into short wavelengths up to THz-band. Operability of Bragg resonator of a novel type has been demonstrated in Ka-band JINR-IAP FEM.
