非互易双各向异性粒子的极化率
Polarizabilities of nonreciprocal bianisotropic particles
摘要：
对于两个非互易电小散射体，建立了极化率的电磁解析模型。这两种粒子都是双各向异性的：所谓的Tele-omega粒子和移动手性粒子。分析结果进行了比较，全波数值模拟。这两种模型都满足主要的物理限制，并且在实验上实现这些粒子的可能性方面没有任何疑问。这篇论文是非互易双各向异性粒子在理想电磁隔离器、扭转偏振器、薄片移相器等器件中应用的必要一步。
英文摘要：
For two electrically small nonreciprocal scatterers an analytical electromagnetic model of polarizabilities is developed. Both particles are bianisotropic: the so-called Tellegen-omega particle and moving-chiral particle. Analytical results are compared to the full-wave numerical simulations. Both models satisfy to main physical restrictions and leave no doubts in the possibility to realize these particles experimentally. This paper is a necessary step towards applications of nonreciprocal bianisotropic particles such as perfect electromagnetic isolators, twist polarizers, thin-sheet phase shifters, and other devices.
