To design metamaterial devices with desired high Q, two enlightening concepts of bound states in continuum (BIC) [34], [35], [36], [37], [38] and guided resonance [39], [40], [41] are introduced in metamaterial optics. Mathematically, the Q values of such two types of modes ...
Analyzing the relationship between the asymmetric parameter and Q-factor, mode I belongs to toroidal dipole bound states in the continuum (TD-BIC). By breaking symmetry, the TD-BIC resonance can be transformed into a TD quasi-BIC resonance with a high Q-factor and strong near-field ...
Toroidal dipole (TD) with weak coupling to the electromagnetic fields offers tremendous potential for advanced design of photonic devices. However, the excitation of high quality ( Q ) factor TD resonances in these devices is challenging. Here, we invest
