Artem Cherepakhin is a recent Master’s graduate of ITMO University. In his two years at the university, he published a number of articles and met a Nobel Prize laureate before deciding to go back to Vladivostok. Artem spoke with ITMO.NEWS about his experiences, research, future plans, and what St. Petersburg and Vladivostok have in common.
Each year, this intense course by ITMO University’s Faculty of Physics and Engineering attracts students and junior researchers from all over the world.
Modern optical devices require constant tuning of their light interaction settings. Lenses need to change focus, lidars have to emit and receive light at different angles. For that purpose, there exist various mechanical apparatuses that shift lenses, rotate reflectors, and move emitters. But what if they all were to become unnecessary? An international research team that includes staff members of ITMO University and the University of Exeter have proposed a new metamaterial capable of changing its optical properties without any mechanical input. This development could result in a significant improvement in the reliability of complex optical devices while making them cheaper to manufacture. The study was featured on the cover of the May 2020 issue of Optica.
On September 14-18, 2020, the capital of Georgia is planning to host the METANANO international conference. Held in Russia over the recent years, the event is venturing abroad to the sunlit city of Tbilisi. Despite the pandemic, the preparations for the conference are still ongoing. The organizers are thinking about how to introduce online formats into the program. Talented students, PhD researchers and young scientists wishing to attend METANANO can partake in a grants competition. Abstracts have to be sent in by March 31. More on the conditions for participation, the program, formats and speakers of the conference in this article by ITMO.NEWS.
The 4th METANANO Conference on Nanophotonics and Metamaterials has recently ended in St. Petersburg. Organized by ITMO University’s International Research Center for Nanophotonics and Metamaterials, the event brought together some 400 researchers from Europe, America, Asia and Africa. In the course of five days, they discussed a wide range of topics, from fundamental research in photonics and plasmonics to business projects in the field of radiofrequency technologies, bionanotechnologies and solar energy. Read on to learn more about the conference and its results.
Physicists from ITMO University have developed the first synthetic dielectric surface where the propagation of electromagnetic waves isn’t hampered by existing defects and can be manipulated. In the future, such a structure will enable the creation of more reliable optical devices and communication circuits. The findings were published in Applied Physics Letters. The project was supported by the Russian Science Foundation.
METANANO-2019: World’s Top Scientists to Celebrate 10th Anniversary of Center of Nanophotonics and Metamaterials in St. Petersburg
METANANO-2019, the fourth conference on nanophotonics and metamaterials, will take place on July 15-19, 2019 in St. Petersburg. Scientists from MIT, ParisTech, and other major scientific centers of the world will discuss the latest advances in science. Each year, the METANANO conference grows in popularity thanks to its expansive range of subjects and a discussion program that’s updated every year in accordance with the latest trends. METANANO-2019 will include symposiums, special sessions, and lectures by renowned scientists.
ITMO University scientist Alexey Slobozhanyuk has been proclaimed the winner of the Jagadishwar Mahanty Prize. Established by the Australian National University (ANU), this annual award is given to the researcher with the best PhD thesis defended in the School of Physics and Engineering of this university. As part of his studies on the joint ITMO University-ANU PhD program, the young scientist researched metamaterials and application of their unique properties in the development of innovative devices of the future, such as highly effective MRI coils and next-generation optical electronic systems. It is this work that was recognized by the prestigious 2018 Prize. In this interview with ITMO.NEWS, Alexey expounds on the prospects for his research field and his experience of doing fundamental and applied research at the same time.
Physicists from ITMO University have developed a model of an optical tractor beam able to capture particles based on new artificial materials. Such a beam is capable of moving particles or cells towards the radiation source. The study showed that hyperbolic metasurfaces have great potential for experiments on the creation of the tractor beam, as well as for its practical applications. The results have been published in ACS Photonics.
A research team from ITMO University and the Australian National University has discovered that different metasurfaces exhibit the same behavior provided a symmetry breaking is introduced to their unit cells (“meta-atoms”). Asymmetry of meta-atoms results in high-quality (high Q) resonances in the transmittance spectra of metasurfaces. Such resonances are capable of multiple amplification of external signals. By manipulating the asymmetry, scientists were able to control the resonances and thus a metasurface’s optical response, which is highly desirable for practical applications. The results of this research were published in Physical Review Letters.
