A novel electromagnetically induced transparency (EIT)-like metamaterial of terahertz domain is proposed. The metamaterial is composed of a single metal wire and a couple metal wires above it. Numerical simulations demonstrate that by rotating the single metal wire around its center, EIT phenomenon is created. The amplitude of the transparent peak increases as the rotation angle increases. When the rotation angle is 60°, the amplitude of the transparent peak reaches its maximum. However, as the rotation angle keeps increasing, the amplitude of the transparent peak gets lower and the peak finally vanishes as the rotation angle equals 90°. We also analyze the sensing performance of the metamaterial with the rotation angle of 60°. The proposed structure is simple and adjustable, with high Q-factor value and good sensing performance.
