• ITMO Researchers Develop Wireless Signal Transfer Method for MRI

  Scientists from ITMO University are the first to prove the possibility of wireless signal transmission in magnetic resonance imaging. Moreover, the resulting images are of even better quality than those produced using the common method of signal transmission over radio-frequency cables. This technology has already passed the first clinical trials on volunteers at the Almazov National Medical Research Center in St. Petersburg. It also received an award by the American Physical Society. The results of the research were published in Magnetic Resonance in Medicine, one of the most reputable scientific journals in the field of medical MRI.

• METANANO-2018 Conference: How to Participate and What to Expect

  The International Conference on Metamaterials and Nanophotonics METANANO 2018 will be held for the third time on September 17-21 in Sochi. Scientists from all around the world will come together to discuss the latest scientific discoveries and achievements; approximately half of the event’s guests will come from foreign universities and research centers. The METANANO conference is becoming increasingly popular due to its large scientific scope. This leads to more interdisciplinary research and, therefore, more practical applications are made for theoretical inventions.

• Alena Shchelokova, Presidential Scholarship Recipient: To Achieve Something, You Have to Get Over Yourself

  Over the course of one’s life, everyone has to make decisions that can change its course and open new opportunities. Alena Shchelokova,  PhD student at ITMO’s Department of Nanophotonics and Metamaterials did not shy away from leaving her home country for St. Petersburg, focusing on a new field of science, participating in a contest and going to Australia to conduct research. The young scientist spoke about how leaving one’s comfort zone can become a h abit and wh y it is essential to know your work’s worth and take pride in it.

• COMSOL DAY: Tractor Beams, Optical Traps and Nanoparticle Manipulation

  At the COMSOL Day in Moscow, head of ITMO’s International Research Laboratory of Nano-Opto-Mechanics Alexander Shalin gave a talk on the new algorithms for multiphysics modeling and optical power calculations using COMSOL Multiphysics software. He demonstrated how the program can be used to model the excitement of unidirectional surface plasmon-polaritons and their optomechanical effect on nano-objects on metal surfaces. Shalin’s team uses these methods to acquire fundamental results in optomechanics and improve the qualities of such technologies as tractor beams, optical trapping, positioning of nanoparticles and other.

• Controlling Propagation of Surface Waves Using Ultra-Small Nano-Antenna

  Physicists from ITMO University, for the first time, theoretically predicted and experimentally demonstrated a method for effectively controlling the propagation of surface waves using an ultra-compact dielectric nanoantenna. In the experiment, the researchers were able to achieve directional launching of surface plasmons. Moreover, the surface plasmons, having wavelengths which differing by only 10 nanometers, spread out in opposite directions. This system allows for the creation of an effective, inexpensive and much more compact demultiplexer, which could be used in the future in devices for optical information processing on a chip. This study was published in the journal Laser & Photonics Reviews.

• International Team Proposes New 3D Topological Insulator Design

  Research in the field of topological insulators is most promising, as it has a wide range of applications. An international research team that includes scientists from ITMO University has recently described the physics of 3D topological insulators in an article published in the Nature Photonics journal. In such systems, photons start to behave as electrons, thus acquiring unique properties. Such systems have great potential for practical application in development of optical chips, stable multichannel communication systems and other optical electronic systems.
