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 â0.65â¯dB and a low reflection of â16.48â¯dB can be achieved at 4.725â¯THz, with the real part of the refractive index equal to â1.9. The FOM of the structure is 89.43, which warrants the quality of the proposed structure for negative refractive index applications.
