Title:
マイクロ波共振器
Document Type and Number:
Japanese Patent JP4176160
Kind Code:
B2
Abstract:
A microwave resonator includes at least one resonant microwave cavity (201; 401) having three mutually orthogonal dimensions and at least one low loss dielectric body (203; 401) substantially enclosing each dimension of the or each cavity. In some embodiments the low loss dielectric bodies are arranged in a stack. In other embodiments the low loss dielectric bodies are concentrically arranged. A resonant mode frequency and a height of a microwave resonant cavity is selected by extending radial bessel function solutions along a radius of the cavity to determine radial locations of electric field nulls of a resonant mode of microwaves, and positioning concentric dielectric tube portions of the bodies substantially at the radial locations of the electric field nulls. Similarly, cavity harmonic function solutions are extended along the axis of symmetry of the cavity to determine axial locations of electric field nulls of the resonant mode of microwaves, and substantially positioning dielectric plate portions of the bodies at the radial locations of the electric field nulls.
