Metamaterials: from Invisibility Cloak to Future Smart Labelling Technology
Speaker Prof. Jun Suk Rho, Pohang University of Science and Technology (POSTECH)
Date 11 March 2024 (Monday)
Time 10:30 - 12:00
Venue Room 3598, Academic Building, HKUST (Lifts 27-28)

The invisibility cloak in Harry Potter and the dreams of invisibility as a superpower are no longer fiction. With the invention of metamaterials, they are theoretically and experimentally possible in real life. Metamaterials — materials that are engineered to have properties that are not found in naturally-occuring materials — allow us to overcome physical limitations. Scientists around the world are researching metamaterials that can be used in diverse sectors, including healthcare, optical display, military affairs, agriculture, and more. For example, metalenses, which can exceed the physical limitations of light, may facilitate leaps in biology and chemistry. The development of metamaterials has just begun, but their potential is limitless. In this talk, I will give a brief overview of metamaterials and metasurfaces: principles, applications and manufacturing methods towards their science-to-technology transition.


Prof. Rho is a Mu-Eun-Jae (无垠斋) Endowed Chair Professor and Young Distinguished Professor at Pohang University of Science and Technology (POSTECH), Korea, with a double appointment in the Department of Chemical Engineering and the Department of Mechanical Engineering. He received his Ph.D. at the University of California, Berkeley (2013), M.S. at the University of Illinois, Urbana-Champaign (2008) and B.S. at Seoul National University, Korea (2007) all in Mechanical Engineering. Prior joining POSTECH, he conducted postdoctoral research in Materials Sciences Division & Molecular Foundry at Lawrence Berkeley National Laboratory, and also worked as a principal investigator (Ugo Fano Fellow) in Nanoscience and Technology Division & the Center for Nanoscale Materials at Argonne National Laboratory. Prof. Rho has authored and co-authored more than 300 high-impact journal papers including Science and Nature. He is also the recipients of several notable honors and awards such as US Department of Energy Argonne Named fellowship (2014), Korean Presidential Early Career Award for Scientists and Engineers (2019), Springer-Nature MINE Young Scientist Award (2020), Elsevier MEE/MNE Young Investigator Award and Lectureship (2020), Member of the Young Korean Academy of Science and Technology (Y-KAST) (2020), Associate Member of the National Academy of Engineering of Korea (NAEK) (2022), NAEK Young Engineers Award (2022), Hong Jin-Ki Creator Award (2022), Fulbright Visiting Scholar Fellowship (2022), Northwestern Simpson Fellowship (2022), Northwestern Eshbach Fellowship (2023), Clarivate Highly Cited Researcher (2023). He serves 14 editorial positions including Light: Science and Applications (Springer-Nature), Microsystems and Nanoengineering (Springer-Nature), npj Nanophotonics (Springe-Nature) and Nanophotonics (De Gruyter).
