    • Experimental Verification of Reversed Cherenkov Radiation in Left-Handed Metamaterial 

      Xi, Sheng; Chen, Hongsheng; Jiang, Tao; Ran, Lixin; Huangfu, Jiangtao; e.a. (American Physical Society, 2009-11)
      By using a phased electromagnetic dipole array to model a moving charged particle, we experimentally verified a reversed Cherenkov radiation in the left-handed media in the frequency range from 8.1 to 9.5 GHz. Our results ...
    • One-Directional Perfect Cloak Created With Homogeneous Material 

      Xi, Sheng; Chen, Hongsheng; Wu, Bae-Ian; Kong, Jin Au (Institute of Electrical and Electronics Engineers (IEEE), 2009-03)
      A one-directional invisibility cloak is presented in this letter. Perfect invisibility can be achieved for TM waves along certain directions. The parameters are just homogeneously anisotropic and relatively easy for practical ...
    • Route to low-scattering cylindrical cloaks with finite permittivity and permeability 

      Xi, Sheng; Chen, Hongsheng; Zhang, Baile; Wu, Bae-Ian; Kong, Jin Au (American Physical Society, 2009-04)
      The method of coordinate transformation offers a way to realize perfect cloaks but provides less ability to characterize the performance of a multilayered cloak in practice. Here, we propose an analytical model to predict ...
