Since J.B.Pendry proposed the concept of "perfect lens" there have been many researches which focus electric fields. However they used 1 dimensional lens. In contrast, this paper suggests 2 dimensional lens calculated from angular-spectrum method. 2-dimensional focusing is achieved in nearfield. This result implies that the proposed lens can be used for wireless power transfer, imaging system, and sensing systems.
