A 0.35-Thz Binary Coding Metasurface Using Glass Integrated Passive Device Technology

This work presents a binary coding metasurface operating at 0.35 THz, implemented using glass-based integrated passive device (IPD) technology. The metasurface consists of binary elements with identical reflection amplitudes but a 180-degree phase difference, enabling beam-splitting functionality through a periodic coding sequence. A fabricated prototype is experimentally validated using a custom-built measurement setup, with results showing strong agreement with full-wave simulations. The demonstrated glass IPD-based terahertz metasurface offers a cost-effective and scalable solution for next-generation wireless communication systems.
