“…Fortunately, it is found that the spoof surface plasmon polaritons (SSPPs) have great potential in the application of microwave and terahertz devices. Due to its characteristics of cut‐off frequency and high confinement, ultrathin corrugated transmission lines, broadband and high‐efficiency transitions, high selective filters and wideband power dividers have been presented based on SSPPs. Therefore, it is possible to design a SSPPs‐based wideband power divider with high‐level harmonic suppression.…”

A novel wideband power divider with ultra‐wideband suppression of harmonics is proposed in this paper. The power divider is composed of double‐sided parallel spoof surface plasmon polaritons transmission line (DSP‐SSPP‐TL) with periodical grooved bow‐tie cells. The cut‐off frequency of DSP‐SSPP‐TL can be flexibly adjusted by changing the parameters of bow‐tie cells. To demonstrate that, dispersion relations of the bow‐tie cells with different parameters are simulated, and three DSP‐SSPP‐TL counterparts are experimented. Then, a power divider centered at 3.31 GHz (f0) is designed, fabricated, and measured. Experimental results indicate that the 10‐dB return loss bandwidth of the proposed power divider is about 146% from 0.9 to 5.73 GHz, and the upper stopband is extended up to 40 GHz (12.1 f0) with the suppression level above 32 dB. Moreover, ultra‐wideband isolation between two output ports of the proposed power divider could be achieved by employing two lumped resistors between two DSP‐SSPP‐TLs.

“…Due to the better characteristics of sspps than a microstrip line, such as low loss, high field confinement, single conductor configuration and the ability to keep signal integrity [2,3], a great number of microwave devices based on sspps have been reported, such as sspps-based filters [4][5][6][7][8][9][10][11], power splitters [12,13] and antennas [14][15][16][17][18][19][20], which will all make a difference in sspps-based wireless communications and other systems.…”

Abstract-We proposed an efficient method to radiate the spoof surface plasmon polaritons (sspps) to the endfire direction, which added two parasitic strips as directors in front of the dipole antenna fed by the sspps structure. The directors were used to enhance the endfire radiation due to its beam modified function. Both simulated and measured results suggest good performance of the proposed antenna in a narrow band from 6.5 to 6.9 GHz with about 7.5 dBi realized gain and a 5 dBi increase in the endfire direction at the center frequency of 6.8 GHz reference to the unloaded structure. Also, the surface electric field distributions of the unloaded and loaded sspps antenna were studied to verify the gain enhancement in the endfire direction in physical perspective. Our work tends to have better performance than other related work, such as broader bandwidth and higher realized gain with even greatly simplified design process. The proposed sspps antenna has potential applications in planer integrated circuits and communication systems.

Multilayer transmissions of spoof surface plasmon polaritons (SSPPs) with high isolations among the multiple channels are presented. For this purpose, a novel SSPP structure that consists of a metallic strip line and a corrugated metallic strip line is proposed, which brings in a solution to overcome the strong coupling of conventional SSPP structures in multiple‐layer applications. Very good isolation properties between two overlapped SSPP waveguides are achieved. More importantly, the property of isolation or coupling between the two overlapped waveguides can be switched by tuning the opening direction of the corrugation grooves. Each channel of the multilayer SSPP system operates independently, making it possible to realize the multilayer multiple‐functional SSPP devices. A prototype of double‐functional device is designed and fabricated, in which two different frequency rejections are achieved in two channels, respectively, without any mutual couplings. Experimental results agree well with the numerical simulations. The proposed design illustrates great potentials in modern plasmonic integrated circuits, opening new vistas in much more complicated multiple‐layer plasmonic systems.
