Transparent structure consisting of metamaterial layers and matching layers

• transparent periodic structure consisting of metamaterial (double negative) layers and matching (single negative material) layers is presented. Through the calculation of the band structure and transmission spectrum, this kind of structure is found to be omnidirectionally transparent to some electromagnetic wave of any polarization. The working frequency and bandwidth can be adjusted by changing the thicknesses of material layers.
