Abstract
A dielectric waveguide resonator includes: a dielectric resonant cavity including a dielectric body and a metal plating layer wrapping an outer surface of the dielectric body; and a metal interface provided in the dielectric body and connected to the metal plating layer, where the metal interface intersects a direction of an intrinsic electric field of the dielectric resonant cavity. The dielectric waveguide resonator includes a blind hole recessed inwards from a surface of the dielectric body, where a bottom surface of the blind hole includes the metal interface, and where an axial direction of the blind hole corresponds with the direction of the intrinsic electric field of the dielectric resonant cavity.
