Abstract: We propose a general method to evaluate the material parameters for arbitraryshape transformation media. By solving the original coordinates in thetransformed region via Laplace-s equations, we can obtain the deformation fieldnumerically, in turn the material properties of the devices to be designed suchas cloaks, rotators or concentrators with arbitrary shape. Devices which havenon-fixed outer boundaries, such as beam guider, can also be designed by theproposed method. Examples with full wave simulation are given for illustration.In the end, wave velocity and energy change in the transformation media arediscussed with help of the deformation view.
