Abstract

We present metamaterial reactors as an innovative class of electrified thermochemical reactors that utilize high-frequency magnetic induction of an open-lattice metamaterial baffle to generate volumetric heat. A central design feature is the modeling of the metamaterial as an effective electrically conducting medium, abstracting its detailed microscopic geometry to a macroscopic susceptor description suitable for reactor-scale electromagnetic characterization. Co-design of the power electronics with the metamaterial provides design rules for efficient and volumetric heating, including the requirement for high induction frequencies. We implement lab-scale reactors with ceramic metamaterial baffles (39 mm in diameter) and megahertz-frequency power amplifiers to perform the reverse water-gas shift reaction, demonstrating reactor operation with near-unity heating efficiencies and radially uniform heating profiles. These clean energy concepts provide a broader context for structured reactors in which volumetric internal heating and complementary reaction engineering properties are collectively tailored to enable ideal operation regimes.

采用高频超材料反应器的电气化热化学反应系统

我们提出的超材料反应器是一类创新的电气化热化学反应器，它利用开放晶格超材料挡板的高频磁感应来产生体积热。其核心设计特点是将超材料建模为有效的导电介质，将其详细的微观几何形状抽象为适合反应堆规模电磁特性分析的宏观受体描述。功率电子器件与超材料的协同设计提供了高效和体积加热的设计规则，包括对高感应频率的要求。我们采用带有陶瓷超材料挡板（直径 39 毫米）和兆赫兹频率功率放大器的实验室级反应器来进行水-气反向转换反应，证明反应器的运行具有接近统一的加热效率和径向均匀的加热曲线。这些清洁能源概念为结构化反应堆提供了更广阔的背景，在这些反应堆中，内部容积加热和互补反应工程特性可共同实现理想的运行状态。
