RESONANCE FILTRATION BY TWO-PHASE RESONATORS

Introduction. Resonance spectral filtration has an exceptional importance for many applications. Resonators based on reflectors with antiphase reflection coefficients two-phase resonators - are proposed. Single-phase and two-phase resonators. Impedance dependencies of single-and two-phase crystal-like structures and single-and two-phase resonators are examined. Frequency dependences of the transmission coefficient for the single-and two-phase resonators are shown. Amplitude-and phase-frequency characteristics of resonators reflectors. The amplitude-frequency and phase-frequency characteristics of resonators reflectors are given. Coming from the condition of phases balance for a two-phase resonator reason of displacement of its transmission coefficient characteristic is set. Two-phase resonator structure correction. The correction of two-phase resonator structure is offered for correction of transmission coefficient characteristic displacement. Exact and approximate dependencies of relative magnitude of resonant cavity length correction from the impedance are shown. Conclusions. Two-phase resonator structures are provided the increase of quality factor in comparing to the traditional single-phase structures. At the set sizes and range of impedances with the increase of impedance of layers from 3 to 10 two-phase resonator quality factor in 1.25...3 times more than single-phase resonator one.
