“…11(a) depicts the simulated loss ratios caused by different factors. It is clear that radiation loss is the main source contributing to the high transmission loss in the lower frequencies, which is mainly caused by the conversion parts [42]. In addition, larger metal loss is observed when conductor material is chosen as tin instead of copper especially for higher frequencies, validating the relatively higher transmission loss of measurements compared with other designs using copper.…”

This paper presents a novel tri-band bandpass filter based on multi-mode spoof surface plasmon polaritons (SSPPs) in microwave frequencies. The combination of multi-mode resonance and cutoff characteristic of SSPPs contributes to a tri-band bandpass response. The proposed SSPPs-based filter consists of two coplanar waveguides, two conversion parts and a SSPPs transmission structure made of five unit-cells. Each unit cell is a multi-mode resonator, which is constructed by a pair of oppositely oriented doubleside folded strips, and the ends of folded strips are placed closely to form coupled-stubs. Two distinct passbands divided by a sharp stopband are produced under the cutoff frequency of SSPPs transmission structure. The third passband above the cutoff frequency is introduced by the resonant tunneling effect due to the self-resonant mode of proposed SSPPs unit cell. Dispersion relations, electric field distributions and proposed equivalent transmission line model give a physical insight into the filter operating mechanism. As a demonstration, a prototype of the proposed filter has been fabricated and measured. The measurement results demonstrate that the proposed filter has a tri-band bandpass performance with excellent frequency selectivity, which may be very useful in many applications, such as multi-band wireless systems. INDEX TERMS Multi-mode resonator, resonant tunneling effect, spoof surface plasmon polaritons (SSPPs), tri-band bandpass filter.

“…As their high confinement, low profile and low loss, the SSP TLs are especially suitable for designing the microwave devices such as filters and antennas [24]- [29]. Subsequently, SSP TLs are widely used to design leakywave antennas (LWAs), dielectric resonator antennas, Vivaldi antennas and multibeam antennas [30]- [36].…”

A continuous beam scanning leaky-wave antenna (LWA) supporting lateral radiation is proposed in this paper. It is based on a spoof surface plasmon (SSP) transmission line (TL) which is a single-layer conductor structure. The proposed SSP TL is slotted periodically with rectangular holes on the metallic strip conductor. Circular patches are loaded periodically along one side of the SSP TL to achieve an additional momentum for converting the slow-wave mode to a fast-wave mode and then modulate the SSP wave into a spatial wave. The proposed SSP LWA produces a single lateral beam rather than double beams usually existed in conventional SSP LWAs, as highly desired in many applications. As operating frequencies increase from 7 to 15 GHz, the proposed SSP LWA achieves a continuous beam scanning range of 65 • from forward to backward with stable high gains. As its primary advantage, this proposed SSP LWA does not lose radiation efficiency even at broadside, which is often suffered by conventional LWAs. Both the transmission characteristics of the SSP TL and the radiation mechanism of the SSP LWA are investigated. Finally, the proposed SSP LWA is designed, fabricated, and measured. The measured results agree well with the simulated ones over a wide operating frequency range, which validates its good performances. The proposed SSP LWAs provide a low-cost solution to planarly integrated communication systems.

“…In order to utilize waves at interfaces of different media, various waveguides have been invented. Goubau lines [5][6][7], as well as spoof surface plasmons [8][9][10][11], support waves at the interface of metals and dielectrics. Dielectric waveguides [12,13], such as fibers, support waves at the interface of dielectrics with different permittivity.…”

Waveguides consisting of artificial media based on periodic structures at the subwavelength scale are a major open topic in contemporary applied physics and engineering. Recent research efforts focus on properties of guided modes in artificial structures. However, as the cornerstone of applications, matching techniques between these interesting waveguides and traditional waveguides deserve more attention. We report a broadband adiabatic mode matching technique for efficient coupling between conventional microwave transmission lines (a coplanar waveguide and a slotline) and one-dimensional (1D) interface waveguides consisting of transverse-electric (TE) and transverse-magnetic (TM) artificial impedance surfaces. The transverse electromagnetic (TEM) mode is transformed to the line wave mode at the 1D impedance-interface adiabatically. Proposed matching techniques open up an avenue for applications of various impedance-interface waveguides.
