“…A slowwave full-mode SIW and a half-mode SIW are demonstrated in [43], [44]. Moreover, by etching rectangular-/cross-/ H-shaped slots on the up-metal layer of SIW [45]- [47], several bandpass filters are also demonstrated. However, these hybrid SSPP-SIW transmission lines and filters are implemented either by using metalized via holes planted on the ground plane or by using etched slots on a single metal layer of SIW, and none of them consider the SSPP unit structures with patterned slots etched simultaneously on double metal layers of SIW.…”

“…As a class of planar waveguide, SIW possesses many advantages of low insert loss, compact size, easy to be integrated [37]- [40], which has been widely applied to various microwave and millimeter devices and components. Recently, the SSPP concept has been introduced to the SIWs [41]- [47]. For example, Zhang et al designed a passband controllable filter by connecting a traditional SIW and an SSPP waveguide based on anti-symmetrical corrugated metallic strips [41].…”

In this paper, we numerically and experimentally demonstrate a substrate integrated plasmonic waveguide (SIPW) concept and its application in microwave bandpass filters. This SIPW consists of double arrays of slots etched on the top and bottom metal layers of a substrate integrated waveguide (SIW) to support spoof surface plasmon polariton (SSPP) modes with low and high cutoff frequencies. The simulated results show that by tuning the parameters of the SIPW's unit cell, the dispersion characteristics can be engineered at will. Then, we propose a sharp roll-off microwave bandpass filter based on this SIPW. This filter has a passband from 7.5 to 13.0 GHz with high return loss and low insertion loss. Furthermore, to demonstrate the independent tuning of the passband of the filter, we also design two microwave bandpass filters with passbands of 9.2-13.0 GHz and 7.5-10.5 GHz by decreasing the distance between two rows of via holes and increasing the slot length, respectively. Finally, to experimentally validate the filter designs, we fabricate and measure three prototypes and find that the experimental results are in excellent agreement with the simulations. This SIPW concept may have extensive potential applications in the development of various plasmonic integrated functional devices and circuits.

In this article, a substrate integrated waveguide (SIW) antenna utilizing odd‐mode spoof surface plasmon polariton (SSPP) for broadside radiation is proposed. Double gratings are etched on the top surface of SIW and the SSPP odd‐mode is excited on this hybrid SIW‐SSPP structure. The proposed SIW antenna has open‐circuit termination and can realize broadside radiation. A prototype of the SIW‐based odd‐mode antenna is fabricated. Reasonable accordance is achieved between measured results and simulated results. The antenna impedance bandwidth is about 5.5% (12.4~13.1 GHz) with |S11| < −10 dB. Stable broadside radiation is also realized within the operating band of 12.3~13.3 GHz and the measured gain varies from 5.66 to 6.34 dB in the frequency band. The proposed broadside radiation antenna is suitable for wireless communication systems due to its compact structure and good radiation performances.

In this letter, odd-mode and even-mode spoof surface plasmon polaritons (SSPPs) supported by complementary plasmonic metamaterial with underlayer ground are investigated. The dispersion characteristics and electric field distributions of the odd-mode and even-mode SSPPs are studied. Different high-efficiency conversion structures are proposed to realize the excitation of odd-mode and even-mode SSPPs transmissions. The odd-mode and even-mode SSPPs transmission lines are simulated and measured. The measured insertion losses of odd-mode transmission line are within 2.58 ² 1.23 dB from 3.0 to 10.0 GHz. The measured insertion losses of even-mode transmission line are within 1.66 ² 1.18 dB from 2.0 to 12.0 GHz. The simulation and measurement results validate the highefficiency excitation and excellent propagation performance of odd-mode and even-mode SSPPs on the complementary plasmonic metamaterial with underlayer ground in the microwave frequencies.
