Electromagnetic Behavior of Representative Metamaterial Structures V. D. Lam Quantum Photonic Science Research Center and Department of Physics, Hanyang University, Seoul 133-791 and Institute of Materials Science, Vietnamese Academy of Science and Technology, Hanoi, Vietnam J. B. Kim, S. J. Lee and Y. P. Lee Quantum Photonic Science Research Center and Department of Physics, Hanyang University, Seoul 133-791 (Received 12 March 2008, in nal form 16 June 2008) We investigated systematically the electromagnetic behavior of di erent magnetic metamaterials, from the split-ring resonator to the cut-wire pair, for providing a negative magnetic permeability. The combination of a cut-wire pair and a continuous wire was also studied experimentally. We found that the combined structure exhibited both leftand right-handed transmission bands. Until the width of the cut-wire pair was increased to merge with the adjacent continuous wire to form the so-called shnet structure, the left-handed (LH) behavior continued to be observed. Finally, the e ect of the structural parameters on the LH behavior of the shnet structure was also investigated. These structures were designed, built and measured in the microwave frequency range.
