“…A significant benefit of this metamaterial is that the asymptotic frequency and dispersion characteristics of the SSPPs can be regulated by the geometrical parameters of the unit element [12][13] . Although many works are available on SSPPs filter structure [14][15][16][17][18][19][20][21][22][23] , this paper introduces a new dimension for filter design in microwave frequency domain based on novel SSPP structure using plasmonic metamaterial. This method is better in respect of sub wavelength confinement.…”

This paper presents the wideband bandpass filter (BPF) in the microwave frequency domain. The realisation approach is based on spoof surface plasmon polaritons (SSPPs) phenomenon using plasmonic metamaterial. A novel unit cell is designed for filter design using an LC resonator concept. Then SSPPs BPF is realised using an optimised mode converter and five unit cells. This paper includes a brief design detail of the proposed novel unit cell. The passband of BPF is achieved at approximately 1.20 -5.80 GHz, 3dB bandwidth is tentatively 4.60 GHz and the insertion loss is less than 2 dB approximately over the passband. The overall dimension of fabricated filter is (90 x 45) mm. A basic schematic of transmission line representation is also proposed to evaluate the BPF structure.

“…To inherit most of the amazing features of SPPs to lower frequencies, researchers have proposed some solutions by etching metal surfaces with periodic grooves or holes to support similar high-confined surface waves, named spoof surface plasmon polaritons(SSPPs) [6][7][8][9]. Thereafter, a series of efforts have been conducted to put the SSPPs into practical uses by constructing smooth bridges between traditional transmission lines and SSPPs waveguide [10,11], the development of SSPPs filters [12,13], waves splitters [14], amplifiers, and other passive and active functional devices in the microwave and terahertz frequencies.…”

A tunable spoof surface plasmons antenna using sinusoidally modulated corrugated reactance surface based on a bulleye structure is proposed in this paper. The designed antenna is made of concentric metallic grooves etched on a metal plate, the depth of which is of sinusoidal periodic variation in the radial direction. This makes it possible that highly confined spoof surface plasmons along corrugated surface can be converted to radiation modes. The proposed bulleye antenna can work from 25.8 to 33 GHz and a bandwidth of 7.2 GHz and its main lobe can be directed at 30 • from the vertical direction at 30 GHz. This antenna has a maximum gain of 15 dB and its main lobe can scan from 14 • to 58 • by tuning the frequency from 28 to 32 GHz.

“…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.
