An optical AND logic device based on chiral surface plasmon polaritons (SPPs) is theoretically proposed. The AND logic device is made up of five Y-shape nanowires with two input ports and one output port. Chiral SPPs excited at the end of input ports propagate along the nanowire. By adding two gold blocks on one side of the AND logic device, the chirality of the device is amplified. By modifying parameters, we find suitable parameters to design the structure with a large chirality at the working wavelength. By setting the threshold, we achieve the AND logic devices. Our structure may provide a significant component in signal transmission and processing devices.

Abstract In this paper, a band-pass filter based on half-mode substrate integrated waveguide (HMSIW) and double-layer spoof surface plasmon polaritons (SSPPs) consisting of two corrugated metal strips is proposed, which can realize band-pass transmission by etching periodic grooves at the top and bottom metal layers of the HMSIW. Moreover, the influences of important parameters on the performance of the proposed band-pass filter are analyzed by parametric study. By changing the key parameters, the low and high cut-off frequency can be controlled independently. The corresponding equivalent circuit of the proposed band-pass filter is put forward to explain the physical mechanism. Compared with the previous structures, this structure features smaller size, wider bandwidth and lower loss. Simulated results show that the proposed band-pass filter achieves a bandwidth (for |S11| < −10 dB and |S21| > −0.8 dB) of about 69.77% (15.6–32.1 GHz). The measured results have good agreements with the simulated ones, which verify that the proposed band-pass filter has good performances and potential applications at the microwave frequencies.
