Omni-directional electromagnetic field concentrators have been recently reported by Marco Rahm et al. [Photon. Nanostruct.: Fundam. Appl. 6, 87 (2008)] based on form-invariant coordinate transformations related to its Jacobi transformation matrix. Using transverse-electric wave illumination, we reduced the complex material parameters of concentrator for future practical implementation. Concentrators with different set permittivity and permeability tensors are proposed. The concentrating performance scattering properties at inner outer boundary these theoretically numerically analyzed. Finally obtain a that simultaneously has perfect matched interior exterior interfaces.
