Abstract
This research presents the simulation, fabrication, and measurement of a new terahertz (THz) metamaterial absorber (MMA). Copper and polyimide are the materials used in this project. The polyimide substrate is sandwiched between the two copper conductor layers. Theoretical results reveal that the absorber has five distinct and significant absorption peaks at 0.994, 0.97, 0.947, 0.904 and 0.892 THz, respectively, with absorption rates of 94%, 99.9%, 99.9%, 97%, and 92%. The electric field, magnetic field, and surface current distributions are used to investigate the structure’s physical mechanism. The incident and polarisation angles of the structure are modified from 0 to 90 degrees to examine the insensitive behaviour of the incident angle and polarisation angle. Laser micromachining and terahertz time-domain spectroscopy are used to build and examine the structure. This work is compared with previous works. It has numerous scientific and sensory applications.
