“…[14][15][16][17][18][19] Recently, there exist several researches of introducing the SSPP into the design of the PDs. [20][21][22] In these previous designs, one H-shaped SSPPs transmission line (TL) was split into two symmetrical U-shaped SSPPs TLs at one specific truncation point through the smooth transition elaborated in Reference 20. In addition, the PD used the coplanar waveguide (CPW) terminals as feeding ports and a flake of graphene was added at the bifurcation point as an isolation resistive film.…”

In this article, a feasible design of an ultra‐wideband power divider (PD) based on spoof surface plasmon polariton (SSPP) is proposed. A quasi T‐junction transmission structure is composed of the sub‐wavelength corrugated grooves drilled on the up metal layer, realizing the wideband and low loss for the propagation of the odd‐mode SSPP wave. The consistency of the dispersion curves between the H‐shaped and the U‐shaped unit cells under the same dimension parameters ensures the smooth transition at the bifurcation point and out‐of‐phase property further. The odd‐mode SSPP is effectively excited by using the microstrip‐to‐slotline convertor. Some design details like gradient corrugations and stepped slotlines are employed to achieve high‐coupling efficiency from the input electromagnetic energy. The simulated and measured results show that the proposed PD achieves 180° ± 5° phase difference over an ultra‐wideband from 3.3 to 9.8 GHz (a relative bandwidth of 99.24%) with high‐transmission efficiency. The ultra‐wideband out‐of‐phase property of this design has potential applications in the differential feed network.

“…26 After that, massive kinds of SPP transmission lines, which consist of different unit structures, have been proposed, including but not limited to H-shaped structures, 27,28 U-shaped structures 29 and S-shaped structures. 30 Since the SPP transmission lines have the advantages of low loss, easy fabrication, etc., various SPP-based microwave devices have been proposed, such as power divider, [31][32][33] frequency splitter, 34 filters, 35,36 couplers, 37 and various forms of antennas and radiators. [38][39][40][41][42][43] Besides, dynamic control of SPP transmission lines is also a research hotspot.…”

By virtue of good liquidity and high conductivity of the liquid metal, a radio frequency (RF) switch based on the spoof surface plasmon polariton (SPP) transmission line is investigated in this paper. The SPP transmission line with H-shaped unit cells are used here and the signal can be successfully blocked by cutting several unit cells. By introducing a micro-channel containing the liquid metal, the SPP transmission line can be reformed with the liquid metal slug. Different states of the switch can be obtained via moving the liquid metal slug by microfluidic technology. The prototype of the presented switch is fabricated and measured and good agreement between the simulation and measurement can be observed. Low insert loss at ON state and high isolation at OFF state can be obtained over the operation band.

“…For example, various plasmonic transmission lines (TLs) have been developed [2,[15][16], and their characteristics also have been thoroughly analyzed by others, these TLs based on SSPPs structures can be used to enhance the EM field confinement, reduce the crosstalk and improve the transmission efficiency. The low loss and high efficiency properties of SSPPs TLs inspire researchers to present different wireless devices, such as antennas [17][18][19][20][21][22], filters, power dividers [27][28][29] and couplers [30][31].…”

An Ultra-Thin and Compact Band-Pass Filter Based on Spoof Surface Plasmon Polaritons

In this work, we report an ultra-thin and compact SSPPs-based waveguide band-pass filter with metals etched on the top surface of substrate, and the side and bottom surfaces of substrate also are covered with metals. The size of this filter is 1.07λ 0 ×0.32λ 0 ×0.02λ 0 (where λ 0 is the wavelength at center frequency). This proposed filter can inherit the merits of rectangular waveguide and SSPPs structure, and its lower cutoff frequency can be tuned by the width of rectangular waveguide, while the upper cutoff frequency can be tuned by the length of complementary comb-like structure. Gradient groove depths are also used to form a smooth transition from rectangular waveguide to SSPPs structure, realizing a good momentum match. The dispersion curves and electric field distributions have been thoroughly investigated to reveal the SSPP-based waveguide filter mechanism. A prototype is fabricated and measured. Both simulations and measurements validate that the band-pass filter proposed in this work has high-efficiency and low-loss transmission properties.
