Abstract

The invention discloses a filter synthesizing an artificial surface plasmon device waveguide and a substrate integrated waveguide. The filter comprises the artificial surface plasmon waveguide and the substrate integrated waveguide. The substrate integrated waveguide comprises a first dielectric substrate and first metallization layers, and two rows of metallization through holes are formed in the first dielectric substrate. The artificial surface plasmon waveguide comprises a second dielectric substrate and second metallization layers, one or more metal grooves are formed in each second metallization layer, the depths of the metal grooves are sequentially increased from the two sides to the middle, the depths of the metal grooves are gradually increased till the depths are the same as the thicknesses of the corresponding second metallization layers, and the opening directions of the metal grooves in the second metallization layers on the upper surface and the lower surface are opposite. The filter has the advantages of being easy to machine, low in cost, small in thickness, low in weight and the like, a common circuit is conveniently manufactured, and high practical value is achieved; meanwhile an ultra-wideband filter and a narrowband filter are provided, and good filtering performance is achieved.

Description

technical field [0001] The invention relates to a filter combined with a waveguide of an artificial surface plasmon device and a waveguide integrated on a substrate, and belongs to the field of new artificial electromagnetic materials. Background technique [0002] New artificial electromagnetic materials (Metamaterials) refer to artificial composite materials with special conduction or radiation characteristics when electromagnetic waves propagate in them. It can also be said to be an electromagnetic material that can be artificially designed to meet specific equivalent permittivity and permeability requirements. . The new artificial electromagnetic material is based on the equivalent medium theory, that is, the equivalent permittivity and permeability can be changed by changing the size of the unit structure of the new artificial electromagnetic material. After more than ten years of development, new artificial electromagnetic materials have been greatly developed, and th...
