摘要

连续介质中的准束缚态（qbic）可以支持具有高质量Q因子的共振。传统上，保持高Q因子需要小α，这给纳米制造带来了重大挑战。相反，我们的研究发现，在具有圆形缺口的硅块组成的超表面阵列中，Q因子随着α的增加而增加。

Increasing of Q Factor of Quasi-Bound States in the Continuum With Increased Asymmetry Parameter in a Silicon Metasurface Array

Quasi-bound states in the continuum (qBICs) can support resonances with high quality (Q) factor. Traditionally, maintaining a high Q factor requires a small α, which brings significant challenges for nanofabrication. In contrast, our study finds an increase in the Q factor with increasing of α in a metasurface array composed of Si blocks with circular notch.
