Reduced permittivity and permeability profiles are proposed based on the electromagnetic transformation theory to achieve spherical reshapers with a split-ring-resonator(SRRs) microstructure. The effective radial permittivity distribution depending on the structure parameters, is obtained to implement a reshaper impinged by a TE incident wave. Finite-element simualtions are carried out and the results show that a good reshaping effect can be achieved at a working frequency despite the reduced and the discreted material parameters as well as unneglectable dipersion and loss effects. And the frequency band can be broadened by choosing proper microstructures such that the resonance point is far from the distribution range of the structural factors.
