Abstract-Controlling the transparency window in terahertz band using mode coupling metamaterials
Mode-coupling are typically with different resonance modes. Controlling couplings among these modes results in a sharp transparency window within the of the Here, we present a of ring and split-ring to constitute a new with entirely new mode. Experimental results show that the asymmetric combination of these can result in a variation in transparency strength. The dimensions and relative positions of the split-ring are discussed particularly with a series of experimental results. Simulation results show that the coupling intensity is the main reason for this behavior. Exploiting this aspect, a way to control the transparency window between is proposed.
