Nanotechnology Discussions podcasts: Electromagnetism at the nanoscale
To celebrate the 150th anniversary of the Maxwell equations, IOP Publishing's Nanotechnology speaks to Professor Jennifer Dionne, Professor Satoshi Kawata and Professor Adarsh Sandhu about electromagnetism at the nanoscale.
The panel introduce some of their research and how it relates to the Maxwell equations. Adarsh Sandhu describes scattering at the nanoscale - "like a small sunset in a testube" – and how it can be applied in biosensing using magnetic nanoparticles, Satoshi Kawata describes how we can play with non-propagating light trapped at surfaces to visualise and fabricate nanostructures and Jennifer Dionne describes how light interacting with non-magnetic materials can induce a magnetic-like response in metamaterials, which can be used in optical 'cloaking'.
The panel provide a little more detail on how scale affects electromagnetic interactions and strategies they have invoked to progress their research exploiting size affects.
The panel describe what they forecast will be key to future developments in research using electromagnetism at the nanoscale, including 3D imaging inside living cells using plasmonic nanoparticles, 3D optical lithography and solar energy conversion.
Professor Jennifer Dionne leads a research group in the Department of Materials Science and Engineering at Stanford University in the US. Her research legacy includes the first demonstration of a negative index material for light at visible wavelengths.
Professor Satoshi Kawata leads the Department of Applied Physics and the Department of Frontier Bioscience, as well as serving as the Executive Director of Photonics Advanced Research Center of Osaka University. He is one of the pioneers in the field of nanophotonics.
Professor Adarsh Sandhu leads research groups at the Tokyo Institute of Technology and Toyohashi University of Technology in Japan where he is also deputy director of the Electronics-Inspired Interdisciplinary Research Institute. He has acted as advisor and consultant for numerous committees and STM publishing boards.
