Abstract We numerically propose a negative refractive index metamaterial structure with a unit cell composed of only one semi H-shaped element. With this structure a very high transmission of −0.65 dB and a low reflection of −16.48 dB can be achieved at 4.725 THz, with the real part of the refractive index equal to −1.9. The FOM of the structure is 89.43, which warrants the quality of the proposed structure for negative refractive index applications.
