    "abstract": "The Doppler effects for the reflected wave from a moving media are\nsystemically analyzed in this paper. The theoretical formula for the Doppler\nshift in the left-handed material, which is described by Drude\u0027s dispersion\nmodel, is presented. This formula is examined by first-principles numerical\nexperiments, which are in agreement with the theoretical results.",
