A meta-atom constructed to make a metamaterial is called a unit cell. The frequency of waves is proportional to the size of the unit cell. The structure's size is less than the incident waves' wavelength. Because the light frequency utilized is Terahertz, the unit cell size is measured in nanometers. Copper is used to create the unit cell geometrical form, which is then deposited on the Rogers substrate. It was created with the researcher's wishes in mind. There is no one-size-fits-all design for any purpose. The purpose of this study is to show how a negative refractive index or a negative index material may bend light waves. The H Shape design has been frequently used to alter electromagnetic waves, but none of them have been successful for higher frequency such as light frequency. The negative value of material characteristics derived from simulations of the metamaterial at three various phases, including phase=0, real value, and imaginary value. As a simulation program, CST Microwave Studio 2018 was employed. All negative values of material attributes acquired at various frequency ranges are shown in the findings. However, for phase=0, the material characteristics are negative, and the imaginary component is acquired across the same frequency range. The negative value for all material attributes happened at different frequencies for the genuine component. This H-Shape design is ideal for controlling light radiation waves.
