“…By constructing a sub‐wavelength surface structure at the interface, the new special EM mode known as spoof surface plasmon polariton (SSPP) or designer SPP (DSPP) inherits the characteristics of SPP at optical frequency and can propagate well along the surface in microwave frequencies 13 . Due to the features of sub‐wavelength localization, strong near‐field confinement, and adjustable dispersion characteristics, SSPP has been taken full use in the novel microwave devices 14‐19 …”

[14][15][16][17][18][19] Recently, there exist several researches of introducing the SSPP into the design of the PDs.

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.

“…Surface plasmon resonances are usually applied in sensor, absorber, and frequency selective surface design [ 15 , 16 , 17 , 18 , 19 ]. In addition, due to the abundant resonant modes exciting a narrow frequency range [ 6 , 7 , 8 , 9 ], the spoof LSP integrated with substrate waveguide structure is proposed to design a wideband BPF with compact size [ 25 ] compared with the filters using SSPPs configuration.…”

“…The resonant modes excited by a plane wave or a microstrip line in disk or ring resonators are depicted as dipole, quadrupole, hexapole, octupole modes, and so on. The sparse resonant modes can be employed to design multiband BPF [ 8 ] or wideband BPF [ 25 ]. However, the higher modes are difficult to excite, and the filters using higher modes have large insertion losses.…”

Design of Wideband Bandpass Filter Based on Corrugated Disk Resonator with Multiple Resonant Modes

et al. 2021

A corrugated disk resonator with eight grooves is proposed for wideband bandpass filter (BPF) design. Due to the spoof localized surface plasmons resonances of the corrugated metallic structure, the dipole, quadrupole, hexapole modes, and a fundamental mode excited by the introduced short-circuited via holes are employed to realize four transmission poles (TPs) in the passband. The theoretical analysis is described by the electric field and current distributions on the resonator. The resonant frequencies can be tuned easily by the parameters of the structure, which can be used to adjust the center frequency and bandwidth of the BPF freely. Furthermore, two resonators are cascaded to obtain eight TPs to improve the selectivity performance. Finally, three fabricated filters demonstrate the design method.

“…[6][7][8][9] The metamaterial approach can also be used to design localized surface plasmons (LSPs) at low frequencies by making corrugations on closed metal surfaces. Spoof LSPs(SLSP) resonators with straight or spiral corrugations have been demonstrated to support multiple resonance modes [10,11] and applied in the design of sensors, [12,13] filters, [14,15] etc. Compared with straight corrugation structures, because the spiral structure accommodates longer corrugations within the same area, the resonance frequency is reduced, giving rise to devices with deep-subwavelength sizes.…”

crosstalk between parallel transmission channels and increase the signal integrity in circuits with dense wiring. [5] Moreover, the dispersion properties of SSPPs can be engineered by tuning the structures of the surface patterning or the bias voltages/currents of the integrated varactor diodes/positive-intrinsic-negative (PIN) diodes, providing flexibility in the design of devices with multiple functionalities or working frequency bands. [6][7][8][9] The metamaterial approach can also be used to design localized surface plasmons (LSPs) at low frequencies by making corrugations on closed metal surfaces. Spoof LSPs(SLSP) resonators with straight or spiral corrugations have been demonstrated to support multiple resonance modes [10,11] and applied in the design of sensors, [12,13] filters, [14,15] etc. Compared with straight corrugation structures, because the spiral structure accommodates longer corrugations within the same area, the resonance frequency is reduced, giving rise to devices with deep-subwavelength sizes. [16] The isolator and circulator are fundamental EM devices that allow nonreciprocal signal routing in photonic and microwave circuits and are widely used in radar, communication, and detection systems. Because the isolator/circulator permits the transmission of EM waves in only one direction, the transfer function can be modified as desired, and the detrimental feedback between different components in the circuit due to unwanted reflections is suppressed. Various mechanisms have been leveraged to achieve such nonreciprocal propagation, including magneto-optical effects, [17][18][19] nonlinearity, [20,21] time modulation, [22][23][24][25][26] near-zero-index metamaterials, [27] topologically protected edge states in photonic crystals, [28] and mode coupling between photonic crystal and resonant system. [29] Among these, the magneto-optical effect is the most commonly adopted, where the symmetry of the electric permittivity tensor is broken by applying an external magnetic field to a ferromagnetic medium. Recently, this mechanism has also been used for designing SSPP isolators and circulators. [30,31] However, these SSPP isolators and circulators are composed of multiple layers of dielectric substrates, SSPP waveguides, and bulky ferrite slabs. Furthermore, the proposed devices usually have only a single operating band.Herein, we report experimental demonstrations of an isolator and a circulator for SSPPs, which are based on the interaction between magneto-SLSP resonator(s) and SSPP waveguide(s). The deep-subwavelength spiral-shaped SLSP resonator coated with the magneto-optical material under a static magnetic field allows surface waves to circulate in A miniaturized spoof plasmonic isolator comprising a deep-subwavelength spoof localized surface plasmon (SLSP) resonator coupled with an ultrathin spoof surface plasmon polariton waveguide is proposed and experimentally demonstrated. The SLSP resonator coated with a magneto-optical material can enhance the isolation property, allowing for multifrequency...
