英文摘要：

A modified design method of electromagnetic metamaterial with generalized curvilinear coordinate transformation based on Maxwell＇s equations is proposed. The transfer equation of the method is introduced, and the feasibility of the design is proved by high gain horn antenna, electromagnetic metamaterial concentrators and electromagnetic metamaterial phase rotation three examples. The conversion formula is used in COMSOL Multiphysics, and the simulation results is obtained and discussed. The simulation results show that through generalized curvilinear coordinate transformation, the artificial electromagnetic metama- terial with excellent field distribution properties can be achieved, and it has more wide feasibility.
