摘要:

在本文中,我们提出了一种新的通用耦合理论的超材料束缚态在连续(BIC)或准束缚态在连续(准BIC),提供超高Q谐振的超材料器件。我们的理论解析地计算了两个亮模的相位耦合。与以前的理论(一个亮模和一个暗模的耦合)相比,我们的方法对超强耦合有更高的精度。因此,我们的理论更适合于BIC或准BIC,我们可以准确地预测的透射谱的超材料BIC或准BIC的第一次。

英文摘要:

In this paper, we present a novel universal coupled theory for metamaterial Bound states in the continuum (BIC) or quasi-Bound states in the continuum (quasi-BIC) which provides ultra-high Q resonance for metamaterial devices. Our theory analytically calculates the coupling of two bright modes with phase. Our method has much more accuracy for ultra-strong coupling comparing with the previous theory (the coupling of one bright mode and one dark mode). Therefore, our theory is much more suitable for BIC or quasi-BIC and we can accurately predict the transmission spectrum of metamaterial BIC or quasi-BIC for the first time.
