Coupled-cavity structures on the base of whispering gallery disk dielectric resonators at millimeter wave band

The computerized experimental stand for investigation of the spectral, power and field characteristics of the open disk dielectric resonators frequency range (50-150 GHz) is described. The main properties of the single and coupled-cavity structures on the base of whispering gallery disk dielectric resonators, such as spectrum of eigenmodes, quality factor and field distribution in wide frequency band was experimentally investigated. Linear and arbitrary configuration of coupled structures was investigated. Preservation of spatial structure of resonant oscillations and increase in quality factor of coupled structures are shown.
