About

Nobuyuki Kaya is a pioneering figure in space-based energy transmission and robotic deployment systems. His research focuses on microwave power transmission (MPT) and large-scale space structure deployment, with a particular emphasis on enabling technologies for Solar Power Satellites (SPS). Kaya’s most notable contributions include the groundbreaking “Furoshiki” deployment concept—a method for unfurling large, flexible antennas in space using a sounding rocket. His 2009 paper on this topic, which has garnered 14 citations, demonstrated the feasibility of microwave power transmission during a rocket experiment, laying critical groundwork for future orbital power stations. Additionally, his work on C-band rectennas (12 citations) advanced the efficiency of wireless power reception for space robots. Kaya also led experiments showing robots crawling on loose nets in microgravity, a key step toward autonomous assembly of large space structures. Though his citation counts are modest, his innovative, hands-on approach—combining sounding rocket tests with practical robotics—has influenced the development of space-based energy infrastructure. Kaya’s research remains essential for students and engineers exploring wireless power transmission and in-space construction.
