We present a symmetry-based scheme to create 0D second-order topological modes in continuous 2D systems. show that metamaterial with \textit{p6m}-symmetric pattern exhibits two Dirac cones, which can be gapped distinct ways by deforming the pattern. Combining deformations single system then emulates Jackiw-Rossi model of vortex, where in-gap bound are guaranteed exist. exemplify our approach si...
