“…In the past years, using plasmonic waveguides as feeders, a few types of antennas have been successfully designed, including dipole [63,64], microstrip patch [65][66][67], dielectric resonator and Vivaldi antennas [68][69][70][71][72][73]. Figure 9(a) introduces the schematic and practicality picture of a dielectric resonator antenna, which was proposed by Kianinejad et al in 2016 [68].…”

Surface plasmon polaritons (SPPs) are interactions between incident electromagnetic (EM) waves and free electrons on the metal-dielectric interface in the optical regime. To mimic SPPs in the microwave frequency, spoof SPPs (SSPPs) on ultrathin and flexible corrugated metallic strips were proposed and designed, which also inherit the advantages of lightweight, conformal, low profile, and easy integration with the traditional microwave circuits. In this paper, we review the recent development of SSPPs, including the basic concept, design principle, and applications along with the development from unwieldy waveguides to ultrathin transmission lines. The design schemes from passive and active devices to SSPP systems are presented respectively. For the passive SSPP devices, the related applications including filters, splitters, combiners, couplers, topological SSPPs, and radiations introduced. For the active SSPP devices, from the perspectives of transmission and radiation, we present a series of active SSPP devices with diversity and flexibility, including filtering, amplification, attenuation, nonlinearity, and leaky-wave radiations. Finally, several microwave systems based on SSPPs are reported, showing their unique advantages. The future directions and potential applications of the ultra-thin SSPP structures in the microwave and millimeter-wave regions are discussed.

“…Spoof surface plasmon polaritons (SSPPs), which are produced by metallic grooves on a substrate, demonstrate characteristics such as a large propagation constant, strong field confinement, and deep-subwavelength properties, akin to surface plasmon polaritons (SPPs) in the optical frequency range [18]. These electromagnetic properties can be manipulated by adjusting the parameters of the grooves [19].…”

In this paper, an antipodal Vivaldi antenna (AVA) with a lower cutoff frequency is proposed based on spoof surface plasmon polaritons (SSPPs) and corrugated edges. Firstly, the gradient slots are etched on the outer edges of the two radiation arms of the conventional antipodal Vivaldi antenna. As a result, the low cutoff frequency is decreased slightly due to the increased surface current path of the antenna. More importantly, the SSPPs structure with identical units is etched on the inner side of two radiation arms, leading to a significant reduction in the low cutoff frequency due to the larger propagation constant of the SSPPs structure compared to the radiation arms of the conventional antipodal Vivaldi antenna. Additionally, the structure of the SSPPs on the stripline ensures effective momentum and mode matching between the quasi-TEM mode and SSPPs mode. Furthermore, to improve the gain at the high-frequency band, the structure of the SSPPs introduced on the inner side of the two radiation arms is further optimized by varying the depths of the grooves. Experimental results demonstrate that the designed antipodal Vivaldi antenna exhibits excellent radiation performance, with a low cutoff frequency of 2.8 GHz and a maximum gain of 9.3 dBi.

“…Spoof surface plasmon polaritons (SSPPs) is a kind of slow-wave waveguide structure, the surface wave is generated by periodically grooving the metal surface. Antennas based on SSPPs can be roughly divided into three categories: leaky-wave antennas, [1][2][3] endfire antennas [4][5][6] and other antennas. 7,8 Among them, leaky-wave antennas have the characteristics of high radiation efficiency, strong directivity and beam scanning capabilities, which can be widely used for radar and wireless communications systems.…”

A broadband circularly polarized (CP) leaky‐wave antenna fed by spoof surface plasmon polaritons (SSPPs) is proposed in this paper. The antenna consists of SSPPs transmission line and the periodic open rings. The periodic open rings are loaded at both sides of the transmission line with 90° phase shift to obtain CP responses. Meanwhile, the antenna can obtain a wide‐angle beam scanning due to the dispersion characteristics of SSPPs. The simulated results indicate that the antenna has a wide CP impedance bandwidth of 44.9% from 3.8 to 6 GHz with a return loss smaller than −10 dB and the antenna axial ratio (AR) lower than 3 dB. Also, the antenna has a wide scanning angle that ranges from −54° to +10°. For validation, the antenna was fabricated and the measured results agreed well with simulated ones.
