Popis: (a) Geometry comprising three uniaxial layers and the angles showing the OA orientations. (b) Fundamental leaky mode in a fully anisotropy-symmetric structure showing PS and INT BICs. Color denotes the e −1 attenuation length of the mode. (c) Fundamental leaky mode with polar anisotropy symmetry broken ( θ f = 85°) shows a single BIC point. (d) Ratio of radiation channel amplitude in dB for the structure in (c).
