Synthesizing quasi-bound states in the continuum in epsilon-near-zero layered materials
Synthesizing quasi-bound states in the continuum in epsilon-near-zero layered materials
Bound states in the continuum (BIC) are highly confined, nonradiative modes that can exist in open structures, despite their potential compatibility and coupling with the radiation spectrum, and may give rise to resonances with arbitrarily large lifetimes. Here, we study this phenomenon in layered materials featuring epsilon-near-zero constituents. Specifically, we …
