“…Recently, Cui's group proposed new dual-beam SSPP LWAs in which the amplitude, radiation angle and polarization of each beam can be designed independently. Similar to the method proposed in reference [94], the dual-beam LWA is made of corrugated metallic strip with bilateral 45 • -tilted grooves which can generate two orthogonal electric-field components as shown in figure 16(a) [96]. The dual-beam LWAs can be easily achieved using periodical modulation based on the superposition theory of aperture fields.…”

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.

“…There are three general methods to achieve periodic LWA of planar structures. One method is to utilize periodic structures on the transmission line itself [9], [17]- [22], such as SSPPs LWAs with periodic impedance modulation [23], SSPPs LWAs that utilize their own periodicity [24], and metagrating [25]- [27] . However, the periodic structure itself can affect the transmission line's dispersion curve, increasing the difficulty of adjustment.…”

In this paper, a wide-angle linearly scanning leaky-wave antenna (LWA) based on spoof surface plasmon polaritons (SSPPs) with a very high scanning rate is proposed. A sine curve period is introduced to construct the SSPPs transmission line in the form of a sine curve, which can transform the dispersion curve to the fast wave region to realize the desired dispersion properties for linearly high scanning rate LWA. The simulated results show that the proposed LWA achieves a scanning angle range of 109° over a narrow operation bandwidth of 7.73-8.13 GHz, implying high linearity, and a high scanning rate. A prototype is fabricated and measured, indicating that the measured scanning angle range is 100° within the frequency band of 7.82-8.21 GHz, and the relative average scanning rate (RASR) is 2053.4°. Compared with ideal linear scanning in the operating frequency band, the mean absolute value error (MAVE) of the measured scanning angle-frequency curve is 1.032°, which validates the proposed design with good agreement between the simulated and measured results. The high scanning rate and scanning linearity performances of the LWAs exhibit great value in reducing both the occupation of electromagnetic spectrum resources and the requirements of accuracy for transmitters and receivers, respectively.INDEX TERMS Leaky-wave antenna (LWA), high scanning rate, linear scanning, spoof surface plasmon polaritons (SSPPs).

“…Spoof surface plasmon polaritons (SSPPs) are special surface electromagnetic (EM) waves with strong confinements existing in the low frequency bands (e.g., terahertz, millimeter wave, and microwave) [18]- [21], which can mimic similar characteristics of surface plasmon polaritons (SPPs) in the optical frequency [22], [23]. Due to the properties of ultra-thin structure [24] and great compatibility with planar circuit [25], the SSPP-based structures have been widely applied in antenna designs, such as leaky-wave antennas [26]- [28], endfire antennas [29], [30], patch antennas [31], [32], and helical antenna [33]. It has been proved that the slow-wave characteristic of SSPPs can be used for miniaturization design [31]- [36].…”

We propose a compact and high isolation dual-polarized antenna array based on plasmonic metastructure operating at 2.58 GHz. The compact principle of the dual-polarized antenna is mainly based on spoof surface plasmon polariton (SSPP) radiation patch to support SSPP modes, which is fed by spatially coupled excitation. Due to the slow-wave feature of SSPPs, the size of dual-polarized radiation patch is reduced to 0.2λ0×0.2λ0, and the total antenna size is reduced to 0.39λ0×0.39λ0, which is much smaller than that of the traditional microstrip antenna with 0.5λ0×0.5λ0. The cross-polarization coupling between two polarization ports can be improved to below -32 dB, showing high isolation characteristics. Besides, a 3×3 compact antenna array is also designed, fabricated, and measured to verify the feasibility of its extension to largerscale antenna systems. Both simulated and measured results of the proposed compact antenna and the antenna array illustrate compact profiles, good ±45 radiation performance, and high isolation levels, which have potential application values for the massive multiple-input and multiple-output (MIMO) base stations.INDEX TERMS Compact antenna, high isolation, dual polarizations, spoof surface plasmon polaritons (SSPPs), multiple-input and multiple-output (MIMO).
