Magnetic effects are at the basis of several relevant microwave applications, e.g., imaging, computer memory modules, magneto-inductive waveguides and metamaterials. Commonly designed at low frequencies, purely natural magnetic molecules are not readily available in the visible, due to intrinsic natural limitations of optical materials. Here, using the anomalous wave interaction of electric-plasmonic nanoparticles, we consider a basic geometry that may constitute a lumped isotropic magneto-plasmonic "molecule" at optical frequencies, with applications for cloaking, imaging and optical communications.
磁效应是多种相关微波应用的基础，例如成像、计算机内存模块、磁电感波导和超材料。由于光学材料的固有自然限制，通常在低频设计的纯自然磁性分子在可见光范围内并不容易获得。在这里，利用电等离子体纳米颗粒的异常波相互作用，我们考虑一种基本几何结构，它可能在光频下构成一种集总各向同性磁等离子体“分子”，可用于隐身、成像和光通信。
