Problems solved by technology

[0004] However, most of the artificial surface plasmon filters currently reported use linear branches or grooves, which have poor confinement of electromagnetic waves, are often large in size, low in transmission rate, and do not have the function of adjusting the passband according to requirements, making it difficult to invest in actual use

Abstract

A miniaturized adjustable band-pass filter based on an artificial surface plasmon relates to an artificial surface plasmon filter. A miniaturized adjustable band-pass filter based on an artificial surface Plasmon is provided, which has a smaller size and can adjust the electromagnetic wave transmission band and enhance electromagnetic wave binding. The filter is provided with a dielectric substrate. A metal structure is arranged on one side of the dielectric substrate. The metal structure is provided with coplanar waveguide feeding structures, an intermediate artificial surface plasmon band-pass filter transmission structure and artificial surface plasmon transition structures. The artificial surface plasmon transition structures are arranged between the coplanar waveguide feeding structures and the intermediate artificial surface plasmon band-pass filter transmission structure. The coplanar waveguide feeding structures are located at the two ends of the dielectric substrate. The filter band is controlled by adjusting the transverse branch length of the hook unit structure. The filter has the advantages of small size, easy processing and high transmission rate.

Description

technical field [0001] The invention relates to an artificial surface plasmon filter, in particular to a miniaturized adjustable band-pass filter based on an artificial surface plasmon. Background technique [0002] Surface Plasmon Polaritons (SPPs) are electron density waves propagating along the metal surface formed by the interaction between the external electromagnetic field and the free electrons in the metal surface region. Since metals have a negative dielectric constant in the optical band, according to the boundary conditions of the electromagnetic field, it can be proved that there are surface plasmons in the optical band on the metal surface. Surface plasmons have two obvious characteristics. First, the wave vector in the propagation direction is larger than the light wave vector. Second, in the direction perpendicular to the propagation direction, the field decays exponentially and has high confinement. This unique transmission characteristic is very beneficial ...
