| 摘 要： | 使用时域有限差分法对四态非厄米系统的耦合模理论进行验证。基于耦合模式方程，给出此系统传输系数公式，计算得出系统的透射谱与反射谱。在CST软件中用开口谐振环设计四态非厄米系统，基于CST软件的时域有限差分法仿真得到系统传输系数并进行验证。计算与仿真得到的传输系数结果一致，表明利用耦合模理论处理四态非厄米系统可行。

| Abstract: | The coupled mode theory of four-state non-Hermitian system is verified by finite-difference time-domain method. Based on the coupled mode equation， the transmission coefficient formula of the system is given， and the transmission spectrum and reflection spectrum of the system are calculated. At the same time， using the split ring resonator to form a four-state non- Hermitian system in CST software， the transmission coefficient of the system is simulated by the finite-difference time-domain method based on CST software. The conclusions obtained by the two methods are completely consistent， which shows that the coupled mode theory is feasible to deal with non-Hermitian systems. |
