Description
Summary:Several techniques have been used to design phase reconfigurable reflecting surfaces for specific conditions. Though, to attain wider beam switching is one of the thirst areas for terahertz communications. Here we propose a reflecting surface based on unit cell structure with PIN diode that is capable of switching beam up to 55° in azimuthal angle on 60° elevation angle. This work partially addresses the non-line of sight (NLOS) problems and allows quasi-line of sight wireless communication at 1.7 THz. Further, studied the impact of PIN diode placement and switching property on beam steerability. The proposed unit cell concept gives a wider switching angle with better angle stability.
