[IEEE 2018 IEEE International Conference on Computational Electromagnetics (ICCEM) - Chengdu (2018.3.26-2018.3.28)] 2018 IEEE International Conference on Computational Electromagnetics (ICCEM) - Beam-Scanning Antenna Excited by Planar Spoof Surface Plasmon Polaritons
摘要： a wide-angle frequency-controlled beam-scanning antenna excited by planar spoof surface plasmon polaritons (SPPs) is proposed in this paper. The scanning angle and the gains of the proposed antenna can reach 83 degrees and 11.5dBi, respectively. The features of high gain, planar structure and wide scanning angle make this kind of antennas have great values in integrated communication systems.

Rejection of Spoof SPPs Using the Second Resonant Mode of Vertical Split-Ring Resonator
摘要： In this letter, the studies of the vertical split-ring resonator (VSRR) at its second resonant mode are carried out for the first time. The VSRR can be regarded as an electric resonator at such resonant mode, which is proven by its resonant current distribution. Then, a new type of rejection plasmonic filter is constructed by adding the VSRR on the planar spoof surface plasmon polariton (SPP) waveguide using double-side corrugated metallic strips. The second resonance of the VSRR is excited by the z-component of the electric field of the spoof SPP mode, near which the SPP propagation is prevented. Utilizing this principle, a plasmonic filter with broadband rejection is designed and fabricated. The measurement result is presented to confirm the highly efficient filtering performance of the proposed filter, which makes it possible to be applied in the advanced integrated plasmonic devices and circuits at microwave and terahertz frequencies.

[IEEE 2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - Guangzhou, China (2019.5.19-2019.5.22)] 2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - A Novel Power Divider Based on Hybrid Circuit of Surface Plasmon Polaritons and Substrate Integrated Waveguide
摘要： In this paper, a novel power divider based on hybrid circuit of spoof surface plasmon polaritons (SPPs) and substrate integrated waveguide (SIW) is proposed. The hybrid circuit consists of three paths including one input branch (SIW) and two identical output branches (spoof SPPs). The pass-band of the power divider is controllable by designing the geometrical parameters of spoof SPPs and SIW, which is because that spoof SPPs and SIW can adjust the upper and lower cutoff frequencies, respectively. Simulated results demonstrated the characteristics of power dividers, such as highly efficient transmission, low loss, and bandwidth adjustable. The combining of spoof SPPs and SIW provides more potential for the development of the integrated functional devices in microwave frequency.
