摘要

用等效电感-电容电路模型可以预测电磁波与磁激励耦合的磁极化子(MP)。然而，当MP和表面声子极化子(SPhP)的共振频率接近时，以往LC电路模型预测的吸收峰与求解电磁场计算结果相差甚远。用时域有限差分(FDTD)方法在理论上证明了SiC狭缝阵列在SiC声子吸收带内的吸收增强。电磁场分布证实了SPhP和MP之间的相互作用。考虑MP1和SPhP相互作用的影响，采用改进的LC电路模型对MP1谐振条件进行预测，给出了多阶MP1谐振条件的预测方法。本研究可为热辐射性能的定向设计和微纳米结构、超材料热辐射性能数据库的建立提供参考。

Predicting Multi-Order Magnetic Polaritons Resonance in SiC Slit Arrays by Improved LC Circuit Model

Magnetic polariton (MP) that couples electromagnetic waves with magnetic excitation can be predicted by equivalent inductor-capacitor (LC) circuit model. However, when the resonance frequencies of MP and surface phonon polariton (SPhP) is close, the absorption peak predicted by the previous LC circuit model are far different from solving electromagnetic field calculation results. Absorption enhancement with a SiC slit array is theoretically demonstrated within the SiC phonon absorption band with Finite-difference time-domain (FDTD) method. The electromagnetic field distributions confirm the interactions between SPhP and MP. Taking the effects of interactions between MP and SPhP into account, the improved LC circuit model is employed to predict MP1 resonance condition and the method for predicting the multi-order MP resonance conditions is given. This study may contribute to the oriented design of thermal radiative properties and micro/nanostructures metamaterials thermal radiative properties database building.
