Dr Georgios Gkantzounis
Georgios Gkantzounis joined the University of Surrey in 2015 as a Research Fellow working on hyperuniform structures. He graduated from the University of Athens, Greece, with a BSc in Physics (2002) with excellence, an MSc in Materials Physics (2004) and a PhD in Photonic Structures (2008) from the University of Athens. Prior to joining the Physics Department at Surrey he worked as a Research Fellow in NCSR Demokritos, Athens Greece (2009-2011) on acousto-optic interactions and as a Research Fellow in California Institute of Technology (2011-2012) on nonlinear elastic dynamics.
Current activities are focused on the physics and applications of non-crystallographic band gap materials both for photon and phonon control, lasing in quasi-random (hyperuniform) structures, phononic structures and acousto-optic interactions.

from a tailored k-space design. Here, we study gold plasmonic hyperuniform
disordered surfaces and, by momentum spectroscopy, we report evidence of kspace
engineering on both light scattering and light emission. Even if the structures
lack a well-defined periodicity, emission and scattering are directional in
ring-shaped patterns. The opening of these rotational-symmetric patterns scales
with the hyperuniform correlation length parameter as predicted via the spectral
