Subwavelength negative index planar terahertz metamaterial arrays using spiral split ring resonators for near field sensing

This study reports new shape of meta-material array structures having electric and magnetic resonances designed for terahertz (THz) frequency band. The proposed structures exhibit left handed meta-material propertiesin THz frequency band. The introduced meta-material split ring resonators in this pa...
