Minyu Zhang is currently pursuing a Ph.D. degree at the Warsaw University of Technology, Warsaw, Poland. He received his B.S. and M.S. degrees from the same university in 2022 and 2023, respectively. His current research focuses on reconfigurable intelligent surfaces (RISs), programmable metasurfaces, reconfigurable reflectarray antennas, antenna theory, and terahertz (THz) communications. His work includes the electromagnetic design, numerical simulation, fabrication, and experimental characterization of antenna and metasurface systems. He is particularly interested in PIN-diode-based digital phase control, beam-steering techniques, modular antenna architectures, polarization characteristics, and practical control circuits for electronically reconfigurable apertures. His broader research interests also include microwave and millimeter-wave engineering, wavefront manipulation, and advanced antenna technologies for future wireless, satellite, radar, and sensing applications.
