Embodiment Construction

[0026] Such as figure 1 As shown, the present invention is based on the artificial surface plasmon and complementary split resonator band stop filter, including the dielectric substrate and the metal structure on it, and the split resonant ring is etched into the metal part of the artificial surface plasmon waveguide superior. The waveguide is a typical artificial surface plasmon waveguide, including a coplanar waveguide 1 , a coupling structure 2 and periodic corrugated metal strips 3 , 4 . Among them, the coupling structure includes a folded structure with gradient grooves and two curved ground structures. Specifically, the coplanar waveguide is located at the end, the ground structure, and one end of the wrinkled structure with gradient groove gradients, and the other end extends toward the direction of the artificial surface plasmon. The artificial surface plasmon is located in the middle, and its two ends are respectively close to the ends of the wrinkled structure with...

Description

technical field [0001] The invention belongs to the field of artificial electromagnetic materials, in particular to a band-stop filter based on artificial surface plasmons and complementary split resonant rings. 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 they are widely used in st...
