IKEZAWA Satoshi

IKEZAWA Satoshi is an Assistant Professor at the Faculty of Science and Engineering, Waseda University, Japan, specialising in metamaterial/metasurface optics, laser spectroscopy and MEMS/NEMS sensors. He received his Doctor of Engineering from Waseda in 2009 and subsequently held assistant and associate positions at Waseda, Kyushu University and Tokyo University of Agriculture & Technology before returning to Waseda in 2023.

Education:

• 2007-2009: Doctoral course, Graduate School of Information, Production and Systems, Waseda University (Ph.D. in Engineering, 2009)
• 2004-2006: Master course, Information Production and Systems, Waseda University

Research interests cover design and nanofabrication of dielectric metasurfaces for holographic movies, varifocal metalenses, polarisation-selective devices, micro-LIBS systems, fibre-optic and environmental sensors, and high-frequency quartz MEMS resonators.

His recent publications (2020-2024) demonstrate a clear trend toward ultrathin multifunctional metasurface optics—integrating holography, beam-shaping, polarisation control and varifocal imaging—using high-index dielectrics (Si, SiN) for visible to LWIR wavelengths, with applications in AR/VR, 3-D displays, optical communications and miniature atomic clocks.

Selected awards:

• Best Presentation – Runner-up, ICST 2024
• Optics Prize, Metaphotonics Research Group, Japan, 2024
• APS Best Applied Paper Award, 2023
• IEEJ Sensor & Micromachine Division Excellent Paper Award, 2023
• Group Technical Activity Awards (IEEJ) 2023 & 2024 for Society 5.0 sensing white-papers

He serves on numerous scientific committees (IEEE, IEEJ, JSAP, LSJ, IMEKO) and has co-authored >80 refereed papers (Scopus h-index 11; Google Scholar h-index 13, 620 citations). His work has been highlighted by IEEE Sensors Council, Optica Publishing Group and AAAS EurekAlert!, underlining technological impacts in miniaturised optical devices and environmental sensing.
