Abstract: 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
paper are constructed using a single loop of conducting wire strip printed over
a very thin low permittivity polyimide dielectric substrate. The effective
parameters like permeability and negative index are extracted from the
simulated complex scattering parameters using direct retrieval method. Unloaded
Q-factor is calculated for proposed terahertz metamaterial resonators. The
proposed arrays are tested by loading different dielectric samples in order to
confirm the testing capability. Significant shift in the transmission is
observed. The reported array structures are novel in terms of their left handed
behavior in THz frequencies. High values of Q-factor reported here, are
suitable for near field sensing applications.
