Locally conformal perfectly matched layer (PML) is extended to a high order FEM combined with curvilinear elements and high order basis functions, which proves accuracy and efficiency. It is able to handle challenging geometries with arbitrary curvatures with few unknown numbers, especially those with curvature discontinuities. Validity of the proposed method is demonstrated.
