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.
Last week, a session of The Social project that brings together people from different professions who aim to learn new things took place in one of St. Petersburg's bars. The project was launched in Switzerland three years ago and now involves about 40,000 people in 12 countries. Its goal is de-virtualization of human communication via the concept of inclusiveness. The organizers invite people from different fields to participate in their meetups, so that the topics would not be limited to just professional interests only and the networking process would take place in a community that is interested in new ideas and trends of the future. At the recent session, Pavel Belov, Dean of Faculty of Physics and Engineering and Head of ITMO’s International Research Center for Nanophotonics and Metamaterials, gave an informal lecture in which he shared his opinions about modern science as seen from Russia.
‘The Unusual Laws of Refraction and Reflection’ is a science-pop book by Soviet physics luminary Robert Silin. In this oeuvre that used to be well-known to every Russian physics buff, Prof. Silin describes the laws that, despite only being discovered at the turn of the last century, have already entered the scientific day-to-day. The book was first sent to press more than 20 years ago in 1999 and is now being republished in a new-and-improved edition with updated terminology and expanded contents. ITMO University’s Faculty of Physics and Engineering staff were instrumental in bringing the book to the 21th century audience. They let ITMO.NEWS in on how the ‘renovation’ project took place and explained the importance of reminding the international scientific community about Russian physicists.
Physicists have managed to create an experimental structure with a strong toroidal dipole response of the electromagnetic field over a wide frequency range. This response is associated with a special configuration of electromagnetic currents causing high concentration of the field. A special dielectric metalattice was created to produce and measure the response. The results can be used to create non-scattering materials, as well as to effectively control electromagnetic fields. The research was published in Advanced Optical Materials.
