Vincenzo Caligiuri works as a Post-Doc researcher at the Department of Physics of the University of Calabria and he is affiliated to the Italian Institute of Technology. He received his master degree in Electronic Engineering in 5/2013 and his Ph.D. in Physics and Materials Science in 5/2017 from Univerisity of Calabria. During his Ph.D. he conducted research activity as a visiting researcher at the Nanoplasm Laboratory (Case Western Reserve University, Cleveland, Ohio), at the Nanotech group at DTU (Copenhagen, Denmark) and at the Lawrence Berkeley Laboratory (Berkeley, CA, USA). He started his research on plasmonics by investigating the optical response of Thue Morse plasmonic quasi-crystals doped with reconfigurable, anisotropic materials. During his Ph.D. he explored the coupling and the propagation of light inside hyperbolic metamaterial meal/dielectric multilayers in the framework of a new propagation regime called Epsilon Near Zero and Pole (V. Caligiuri et. al., Sci. Rep., 2016, 6), experimentally demonstrating the possibility to realize noticeably applications such as supercollimation, perfect lensing and so on. Moreover, by adding a suitably designed gain material, he demonstrated the possibility to reach a completely new propagation regime called Resonant Gain Dielectric Singularity (V. Caligiuri et. al., ACS Nano, 2017, 11 (1), pp 1012-1025) in which the new developed HMM configures as a promising candidate for metamaterial nano-lasers.
