  A novel digital reconfigurable 2_bit metamaterial, equipped with a substrate
integrated feeding system, is designed for industrial quality control
applications within the terahertz frequency range. The proposed feeding
mechanism facilitates azimuthal beam steering, spanning from negative 90 degree
to positive 90 degree, thereby enabling the reconfiguration of beam patterns
within the digital metamaterial. Utilizing the phase distribution concept and
comprehensive analysis of coupling and the e_field effect on individual unit
cells, the metamaterial array spacing is meticulously designed. Operational at
0.7 THz, the system offers versatile reconfigurability, supporting single,
dual, and multibeam modes. Through meticulous optimization, the system
demonstrates an impressive negative 138 degree to positive 138 degree beam
steering capability. This dynamic beamforming ability, transitioning seamlessly
from a singular beam to multibeam configurations, requires minimal
software-hardware integration for scanning and inter_satellite links, thus
presenting significant potential for enhancing product quality within
industrial environments and satellite communication.
