A Low-Cost 1-Bit PIN-Diode Reconfigurable Intelligent Surface for the 5G NR n78 Band: Unit-Cell Design, Column-Biased Fabrication, and Anechoic-Chamber Characterization

This paper reports a 10×10 1-bit reconfigurable intelligent surface (RIS) for the 5G NR n78 band, built for under USD 250 and used as a measurement-validated test vehicle: every as-built non-ideality is carried through the analysis, and every measured quantity is compared with si...
