Abstract
Bound states in the continuum (BICs) are lossless states predicted in quantum mechanics in 1929, and for the last decade, received special attention in optics and photonics as a versatile tool to achieve giant quality factors (Q factors) [1]. For ordered arrays of subwavelength meta-atoms, metasurfaces, with broken in-plane symmetry, it was shown that Q factor of quasi-BICs can be unambiguously controlled by variation of the unit cell asymmetry parameter [2].
