Terahertz metasurface based on additive manufacturing technology

We compare and analyze terahertz (THz) metasurfaces fabricated using two distinct additive manufacturing (AM) technologies, i.e., printable electronics (PE) and three-dimensional (3D) printing. With terahertz time domain spectroscopy (THz-TDS), the performance of these devices was investigated. Both samples’ transmission characteristics were consistent with simulation results, demonstrating the effectiveness of the manufacturing technique and that they can be widely used for bandpass filtering applications at a low cost.
