An Optics + Photonics 2018 Plenary Presentation Recording

Bumki Min, KAIST (Korea)

Energy conversion in a physical system requires time translation invariance breaking according to Noether's theorem. Closely associated with this symmetry-conservation relation, the frequencies of electromagnetic waves are found to be converted as the waves propagate through a temporally varying medium. Thus, effective temporal control of the medium, be it artificial or natural, through which the waves are propagating, lies at the heart
of linear frequency conversion.

In this plenary presentation, Bumki Min of KAIST (Korea, Republic of) explains the basic principle of linear frequency conversion in a rapidly time-variant metadevice and show various interesting properties and future prospects of rapidly time-variant metadevices.

Bumki Min is an associate professor in the Department of Mechanical Engineering at KAIST. His main research interests include metamaterials and micro/nanophotonics.

He received his BS and MS degrees in electrical engineering from Seoul National University in 1999 and 2001, and MS and PhD degrees
in applied physics from Caltech in 2003 and 2006, respectively. After graduation, he worked as a postdoctoral scholar at Caltech and UC Berkeley.
