Abstract

In this paper, the design and analysis methods of Liquid crylstal phase shifter (LCPS) with high performance based on nanowire filled membrane (NaM) and spoof surface plasmon polariton (SSPP) are proposed. The equivalent transmission line model and distributed circuit parameters of a NaM-LCPS are constructed and compared with those of a conventional microstrip line liquid crystal phase shifter (ML-LCPS) to reveal the causes of the high figure of merit (FoM) of the NaM-LCPS. Building upon above analyses, an idea of combination of SSPP and NaM-LCPS is proposed to improve the NaM-LCPS's performance. Simulation results show that the NaM-SSPP-LCPS reaches an outstanding FoM of 123.5°/dB and a per wavelength phase shift of 377.5°/λ0, however, NaM-LCPS only has a FoM of 98.9°/dB and a phase shift of 241°/λ0 per wavelength, which increases by 24.87 % and 56.64 % compared to the NaM-LCPS, respectively, implying higher efficiency and more compact physical size.

期刊介绍： Published since 1969, the Microelectronics Journal is an international forum for the dissemination of research and applications of microelectronic systems, circuits, and emerging technologies. Papers published in the Microelectronics Journal have undergone peer review to ensure originality, relevance, and timeliness. The journal thus provides a worldwide, regular, and comprehensive update on microelectronic circuits and systems. The Microelectronics Journal invites papers describing significant research and applications in all of the areas listed below. Comprehensive review/survey papers covering recent developments will also be considered. The Microelectronics Journal covers circuits and systems. This topic includes but is not limited to: Analog, digital, mixed, and RF circuits and related design methodologies; Logic, architectural, and system level synthesis; Testing, design for testability, built-in self-test; Area, power, and thermal analysis and design; Mixed-domain simulation and design; Embedded systems; Non-von Neumann computing and related technologies and circuits; Design and test of high complexity systems integration; SoC, NoC, SIP, and NIP design and test; 3-D integration design and analysis; Emerging device technologies and circuits, such as FinFETs, SETs, spintronics, SFQ, MTJ, etc. Application aspects such as signal and image processing including circuits for cryptography, sensors, and actuators including sensor networks, reliability and quality issues, and economic models are also welcome.
