Abstract

The invention relates to a real-time controllable waveguide structure based on a ferroelectric film, and belongs to the technical field of waveguides. The real-time controllable waveguide structure comprises a dielectric plate, a metal micro-strip, metal blocks and ferroelectric film rectangular resonators; the metal micro-strip is fixedly connected to one surface of the dielectric plate, a plurality of grooves are formed in two side edges of the middle part of the metal micro-strip, and the plurality of grooves form an artificial surface plasmon structure; the metal blocks are in one-to-one correspondence with the grooves, and the metal blocks are respectively arranged in the corresponding grooves and are fixedly connected with one surface of the dielectric plate; and the ferroelectric film rectangular resonators are arranged at the two sides of the metal block, and coupling gaps are reserved between the ferroelectric film rectangular resonators and the groove walls of the corresponding grooves. The real-time controllable waveguide structure can regulate and control the transmission passband bandwidth in real time, and can realize broadband impedance matching and reduce reflection loss.

Description

technical field [0001] The invention belongs to the field of waveguide technology, and in particular relates to a real-time controllable waveguide structure based on a ferroelectric film. Background technique [0002] With the advent of the era of big data, the information capacity of wireless communication has increased rapidly, and wireless communication systems require the manufacture of microwave devices with higher integration, more stable working characteristics, and more diversified functions. [0003] However, with the completion of processing, the functions of traditional analog microwave devices are fixed and cannot be adjusted in real time, which is not conducive to the adaptation of microwave devices to complex applications. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a ferroelectric film-based real-time controllable waveguide structure, which can real-time control its transmission passband b...
