But at the same time as the cut-off frequency is reduced, the confinement of the transmission line to the wave is strengthened due to the increase of h, which leads to the reduction of the transmission distance
Adjusting the cutoff frequency by increasing h, or adding additional structures tends to increase the lateral dimension of the transmission line; affecting the transmission efficiency of the transmission line

Abstract
The invention relates to a miniaturized artificial surface plasmon transmission line based on an interdigitated structure. It includes a dielectric substrate, a metal slot line, two matching units and two microstrip feeders; the metal slot line and the matching unit are located on the same side of the dielectric substrate, and the microstrip feeder is located on the other side of the dielectric substrate; one end of the two matching units is connected to the The metal slot line is connected, and the other ends are respectively overlapped with two microstrip feeders. Two matching units and two microstrip feeders are arranged symmetrically at both ends of the metal slot line; the metal slot line includes a plurality of slotted units, and an interdigitated structure composed of a plurality of metal strips is arranged in the slotted units. The invention has high-efficiency transmission characteristics, and on the premise of keeping the line width of the transmission line unchanged, it realizes the electromagnetic wave cut-off characteristic of lower frequency, realizes the miniaturization design of the transmission line, and can quickly realize specific and different degrees of miniaturized artificial surface plasma Exciton transmission lines. It has the characteristics of low crosstalk and high efficiency, improves space utilization, is convenient for processing and production, and has low cost.
Description
technical field [0001] The invention belongs to the field of novel artificial electromagnetic materials, in particular to a miniaturized artificial surface plasmon transmission line based on an interdigitated structure. Background technique [0002] Surface plasmon polaritons (surface plasmon polaritons) are a special electromagnetic response generated at the interface between metal and dielectric. In the natural state, it generally exists in high-frequency bands such as near-infrared and optical bands, and manifests as a form of surface wave propagating along the metal surface at the interface between the metal and the medium. The electric field of the surface wave decays exponentially along the normal direction of the interface, which has a strong binding property. Due to the high-intensity confinement of light at subwavelength dimensions, surface plasmons are widely used to break through the diffraction limit and build various highly integrated optical components and cir...
