摘要

超穎材料利用有效介電常數(ε(下標 eff))及有效透磁率(μ(下標 eff))來處理其電磁性質，這成功地處理很多由超穎材料引生出前所未有的電磁新現象，包含人工磁性材料、負折射率材料、完美透鏡、隱形斗篷、完美吸收器等等，這兩個巨觀物理量（ε(下標 eff)及μ(下標 eff)）無法清楚地解釋一些有關超穎材料的新現象，如：超穎材料的光學穿透量增強(Enhanced Optical Transmission, EOT)機制、電磁誘發穿透(Electromagnetically Induced transparency, EIT)等。故研究者於近年來，嘗試將電漿子理論引入超穎材料，並提出新的名詞－電漿子超穎材料(Plasmonic Metamaterials)，以解釋EOT或是EIT等等新現象。最後我們也敘述了新的領域－介電超穎材料。

Recently, metamaterials by employing the concept of effective permittivity and permeability have sucessfully described the unprecedented electromagnetic phenomena, including artificial magnetic atom, negative index of refraction, perfect lens, invisible cloak, perfect absorber and so on. However, these constitutive parameters could not explain special cases such as enhanced optical transmission (EOT), electromagnetically induced transmission (EIT) and so on. Therefore, researchers recently try to merge the plasmonics theory with metamaterial in order to solve these problems, and create a new word-plasmoric metamaterials. In this communication, we will introduce some papers about plasmoric metamaterials. Finally, we will review metamateials made of dielectric which are the new field of metamaterials.
