【摘要】：系统地阐述了超颖材料在无线电能传输中应用时所涉及到的部分理论与设计方法。从不同的出发点解释了超颖材料改善无线电能传输性能的作用机理,分别介绍了超颖材料的负折射效应,磁偶极子耦合模型和电磁坐标变换理论。此外,为说明如何实现超颖材料所需的电磁本构参数,还介绍了两种超颖材料的设计方法:原理模型法和S参数反演提取法。原理模型法推导得到简单形状的超颖材料人工介质微结构单元的电磁参数,对获取电磁参数具有一定的启发意义;而实际设计中通常采用S参数反演提取法,通过有限元仿真及反演公式得到结构更复杂的人工介质微结构单元的电磁参数。
[Abstract]:Some theories and design methods involved in the application of superglume materials in radio energy transmission are systematically expounded. The mechanism of superglume materials in improving radio energy transmission performance is explained from different starting points. The negative refraction effect, magnetic dipole coupling model and electromagnetic coordinate transformation theory of superglume materials are introduced respectively. This paper also introduces two design methods of superglume material: principle model method and S parameter inversion extraction method, the principle model method deduces the electromagnetic parameters of simple shape superglume material artificial medium microstructure unit. In the practical design, the S-parameter inversion extraction method is usually used, and the electromagnetic parameters of the artificial medium microstructural unit with more complex structure are obtained by finite element simulation and inversion formula.
