Project Description

Surpassing the known limits for the performance for specific class of devices has been always a challenge for scientists and researchers regardless of their domains of interest. This proposal concerns similar scientific quests in photonic structures with use of ordinary media. In particular, it describes optimal models and designs where controlling of electromagnetic waves with respect to various characteristics such as transmitted power, radiation or direction of propagation, becomes feasible through photonic synthetic media. The first objective aims at investigating/modeling frequency-selective super-transmission in eutectic (materials with easy liquidification and solidification) structures of self-organized Zinc Oxide (ZnO) lamellas into Zinc Tungstate (ZnWO4) and the construction of them. The second objective concerns the super-radiation in ultra-efficient hybrid Light Emitting Diodes (LEDs) and the computationally fast optimization of the corresponding design. A fabrication of prototypes and the corresponding measurement process has been also programmed. The third objective pertains to anomalous reflection and transmission from simple metasurfaces, which can be used as alternative simple design of superlenses.
This proposal will act as a vessel of bringing several young Kazakh scientists in contact with the forefront of global research within the broad area of Photonics. Building the next generation of researchers in Kazakhstan according to the global standards will get benefitted by the execution of projects presented in this proposal. In particular, several research visits of members of the Astana team, as we call the group working at NU, have been planned at top places of experimental testing (Moscow, Warsaw, Southampton) and will constitute valuable experience for them. Furthermore, the elaboration of theoretical topics under the supervision of PI locally, will be useful for them since PI will carry to Kazakhstan modern methods of research management based on his tenures at various diverse environments (NTUA@Greece, Aalto@Finland, UTAustin, and Harvard).
It should be stressed that this proposal will fund the theoretical part of the first two Objectives (I and II) and the entire the third Objective (III). The Astana (local) team will mainly execute the modelling, design and simulation, while having auxiliary role in the experimental testing and measurement which will be carried by the groups of the external collaborators.
