Georgia Papadakis

Graduate Student


Georgia obtained her B.S./M.S. in Electrical and Computer Engineering from the National Technical University of Athens (NTUA), Greece in 2011. Her master thesis was a study of broadband plasmonic structures for datacom applications, conducted in the Photonics Communication Research Laboratory of NTUA. From 2011 to 2012 she worked in the area of radio frequency linear particle accelerators at CERN, Switzerland. Georgia joined the department of Applied Physics in Caltech in 2012, as a graduate student. Georgia’s research pertains to modeling and experimental characterization of optical metamaterials.  She is investigating inverse-problem methods for retrieving metamaterials electromagnetic parameters. At the same time she works on tunable metamaterials and phenomena arising from active tuning of their optical response, such as tunable high/low permittivity metamaterials, applicable to imaging/sensing applications and simple quantum operations.

Georgia is a National Science Foundation Graduate Research Fellow (GRFP) since 2013. She has also been awarded the MRS best poster award ( for her work on transparent conductive-based tunable metamaterials along with another recent CMPI poster award on graphene-based metamaterials (
