Basic ideas of negative refractive index metamaterials were introduced.Then proposed negative refractive index structure were discussed,such as split ring resonator（SRR）,photonic crystals and distributed L-C networks that these materials may hold for realizing new and seemingly exotic electromagnetic phenomena,and recent advances in metamaterials research were given.Its application and prospect such as new science and RF/microwave passive devices were given. 负等效介电常数 负等效磁导率 负折射率 开口谐振环 negative dielectric constant negative magnetic permeability negative refractive index split ring resonator O482 电波环境及模化技术国家重点实验室基金资助 2005-01-01 2021-04-01 S2
