Abstract
Based on the theory of transformation optics and concept of complementary medium, a kind of electromagnetic refractor and wave splitter using homogeneous metamaterials with negative refraction index is proposed. The operating mechanisms are described and constitutive tensors of the complementary medium are derived. Full wave simulations are performed to confirm the functionality of the proposed devices. Simulation and calculation results verified that this approach can be further utilized to design novel waveguide bends structure with different cross section width and angle using homogeneous metamaterials with negative refraction index, in addition, the simulations results show that nearly all the energies are transmitted and there is no wave fronts distortion when wave transmits through the bend.
