“…Recently, two different methods of realizing SSPP tunneling have been proposed. 31,32) The SSPP tunneling proposed by Joy et al 31) is a resonant tunneling supported by a SSPP guide with a defect cell, and the tunneling frequency is inside the band gap of the SSPPs. Using epsilon-near-zero (ENZ) metamaterials, Li et al 32) realized tunneling within the pass band of the SSPPs.…”

In this work, we realize tunneling propagation through spoof surface plasmon polariton transmission lines loaded with magnetoinductive metamaterial channels above a high cutoff frequency. Magnetoinductive metamaterial channels consist of split-ring resonators, and two different structures are proposed. Samples are fabricated, and both measurements and simulations indicate a near-perfect tunneling propagation around 17 GHz. The proposed methodology could be exploited as a powerful platform for investigating tunneling surface plasmons from radio frequencies to optical frequencies.

“…1(a) are regular, which is a representation of the present SSPP filter design approach whose parameter variation tendencies are fixed. In that way, the SSPP parts are periodical and the variation steps of mode conversion units are fixed [8,15–17]. Specifically, in the mode conversion parts, the steps between the vertical bars' lengths, the spacings between the vertical bars and the gradient of the entire slope, all remain unchanged [11,13,18–20].…”

This paper presents a low insertion loss low-pass filter based on the spoof surface plasmon polariton (SSPP) with single comb-shape. Compared with traditional ones, the proposed filter provides lower insertion loss and return loss by optimizing the structural parameters of the mode conversion and SSPP parts. According to the measurement results, the average insertion loss of the fabricated filter is 0.41 dB and the return loss of which at the near-zero-hertz band is <−25.9 dB. The S parameter comparison result between the unoptimized and optimized filters demonstrates that the optimized filter provides lower insertion loss and return loss, smaller size, and better out-of-band rejection. The dispersion comparison result reveals the reasons behind the improved performances. The better performances of the optimized filter proves that breaking the regularity of traditional SSPP filters is beneficial to the filter's performances.

“…Epsilon-near-zero (ENZ) materials refers to those materials with a near-zero relative permittivity and owing to the special physical characters, they are widely used in researches of metamaterial and metadevices. In the past two decades, researchers reported several types of devices based on ENZ materials, in which the EM energy squeezing and tunneling (EST) were observed [14][15][16][17][18]. Moreover, utilizing metamaterials and metasurface are believed to be an efficient way to realize EM EST [19,20].…”

Energy squeezing attracts many attentions for its potential applications in electromagnetic (EM) energy harvesting and optical communication. However, due to the Fabry-Perot resonance, only the EM waves with discrete frequencies can be squeezed and, as far as we know, in the previous energysqueezing devices, stringent requirements of the materials or the geometrical shape are needed. We note that the structures filled with epsilon-near-zero (ENZ) mediums as reported in some works can squeeze and tunnel EM waves at frequencies (e.g. plasma frequency). However, the group velocity is usually near zero which means few EM information travel through the structures. In this paper, low-loss energy squeezing and tunneling (EST) based on unidirectional modes were demonstrated in YIG-based one-way waveguides at microwave frequencies. According to our theoretical analysis and the simulations using finite element method, broadband EST was achieved and the EM EST was observed even for extremely bended structures. Besides, similar EM EST was achieved in a realistic three-dimensional remanence-based one-way waveguide as well. The unidirectional modesbased EST paving the way to ultra-subwavelength EM focusing, enhanced nonlinear optics, and designing numerous functional devices in integrated optical circuits such as phase modulator.
