【摘要】 本文提出了一种工作在太赫兹频段的基于人工表面等离激元的双模传输线。该结构把偶模和奇模的激励设置在同一金属层,偶模激励通过一段传输线与弧状结构实现,奇模结构通过传输线直接对地层的缝隙进行激励。为了验证所提出的双模传输线,使用CST软件在玻璃基上设计一种8单元对称结构的人工表面等离激元双模传输线。双模传输线工作在在频率1.7THz到2.2THz范围内,S11和S33在-10dB左右、S21和S43大于-5dB、S41和S23基本小于-10dB。与已有文献相比,该双模传输线拥有结构简单、便于激励等优势,可降低双模传输线的使用空间,有望在实现芯粒之间的高速互连中得到广泛应用。更多还原

【Abstract】 This paper proposes a dual-mode transmission line based on spoof surface plasmon polaritons that works in the terahertz frequency band. The structure sets the excitation of the even mode and the odd mode in the same metal layer. The even mode excitation is realized through a section of transmission line and an arc-shaped structure, and the odd mode structure directly excites the gap in the stratum through the transmission line. In order to verify the proposed dual-mode transmission line, an 8-unit symmetrical artificial surface plasmon dual-mode transmission line was designed on a glass substrate using CST software. The dual-mode transmission line works in the frequency range of 1.7THz to 2.2THz, with S11 and S33 around-10dB, S21 and S43 greater than-5dB, and S41 and S23 almost less than-10dB. Compared with existing literature, the dual-mode transmission line has the advantages of simple structure and easy excitation, which reduces the use space of the dual-mode transmission line and is expected to be widely used in realizing high-speed interconnection between core particles.更多还原
