标题： Proposal for an electrically controlled terahertz micro-oscillator

摘要： 一种能够产生由施加电压控制的持续太赫兹电磁辐射（振荡器）的源被提出。该结构包括一个含有金属纳米棒的纳米复合板，该纳米棒夹在两个静电栅控石墨烯片之间。其工作原理基于纳米棒极化从石墨烯镜面反射的辐射中经历的正反馈。所提出的方法可以提供一种微观的单色偏振太赫兹辐射源，其功率足以用于生物医学和安全应用。 显示英文摘要

摘要： A source which generates sustained terahertz electromagnetic radiation (oscillator) controllable by an applied voltage is proposed. The structure consists of a nanocomposite slab containing metal nanorods enclosed between two graphene sheets which are electrostatically gated. The principle of its operation is based on a positive feedback which the nanorods polarization experiences from the radiation reflected by the graphene mirrors. The proposed approach can provide a microscopic source of monochromatic polarized terahertz radiation of power sufficient for biomedical and security applications.
