Researcher: Shuya Iwamatsu
Researcher CV: Shuya Iwamatsu received the Bachelor of Engineering from Osaka University, Japan, 2020. His bachelor´s degree concentrated on resonant tunneling diode (RTD) oscillators for terahertz (THz) wireless communications. He is currently doing the master thesis toward the M.E. on coherent power combining of RTD oscillators with graduate school of engineering science, Osaka University. Since 2021, besides that, he started in the University of Duisburg-Essen a new work on photonics-assisted THz beam steering systems in TERAOPTICS project.
Research objectives: Due to the high free-space path loss at THz frequencies, moderate output powers and receiver sensitivities, future mobile THz applications such as THz communications but also mobile THz sensing for material identification (security, material science) must utilize meta-surfaces providing directive and steerable THz beams. The aim of this research is to investigate approaches for THz beam steering (Challenge II) and to integrate photonic phase shifters and wideband optical true-time-delays with mediated THz sources developed in the network (Challenge V) to demonstrate <1 THz beam steering.
Expected results: Optically mediated antennas array providing directive and steerable beams at up to 1THz.
