摘要

在本工作中，我们从实验和理论两方面研究了导电空心球的电极化率，作为一个基本的电磁参数，可以用于表征任何微观和宏观尺度的单个非磁性物体:原子、分子、粒子等。在ku波段(12-18 GHz)，利用矩形波导微扰腔研究了不同直径(2-5 mm)中空导电球的极化率。提出并验证了微波范围内元原子极化率计算的简单解析模型。研究结果表明，利用具有可控尺寸和导电性的空心球体作为超原子用于微波超材料设计具有重要的潜力。

Characterization of Individual Hollow Spheres Metaatoms in Microwaves

In the present work, we study, both experimentally and theoretically, the conductive hollow spheres’ electrical polarizability as a fundamental electromagnetic parameter that can be applied for the characterization of any individual non-magnetic object of micro- and macroscopic scale: atom, molecule, particle, etc. The polarizability of individual hollow conductive spheres of different diameters (2-5 mm) were investigated using a perturbed rectangular waveguide-based cavity in Ku-band (12-18 GHz). The simple analytical model for metaatoms’ polarizability calculations in the microwave range was proposed and verified. The obtained results demonstrate significant potential for using hollow spheres with controlled size and conductivity as metaatoms for microwave metamaterials design.
