主　　题：hyperbolic symmetry polar 

摘      要：Subwavelength-scale manipulation of electromagnetic waves forms the cornerstone of next-generation photonic devices and quantum information processing[1],where extensive efforts have focused on momentum-frequency dispersion through modification of the sizes,shape topology,and symmetry of the isofrequency contours(IFCs)[2,3].For instance,twisting of the multi-layers of stacked vdW materials results in a topological transition from open(hyperbolic-like)to closed(elliptical-like)IFCs(i.e.,control of the propagation wavefront).In contrast,the symmetry of IFCs,which is deeply rooted in the system symmetry,is more difficult to modulate[4].For example,hyperbolic polaritons exhibit four mirrorsymmetric beams in high-symmetry orthorhombic crystals,while asymmetric propagation of tilted hyperbolic shear polaritons only emerges in low-symmetry monoclinic crystals[3].
