テラヘルツ帯２次元円孔配列フォトニック結晶の透過特性

Transmission properties of 2-dimensional dielectric and metallic photonic crystals with trigonal hole arrays have been investigated in the terahertz region. The transmission spectra are quite different between the dielectric and metallic photonic crystals, i. e. the characteristics of the former is explained by folding of the wave-guide mode of the slab into the first-Brillouin zone by the periodic structure and that of the latter is explained by the transmission through the isolated metallic wave guides and by the Wood’s anomaly.
