  • New Generation of Wireless Chargers Developed at ITMO: Here’s How It Can Change Your Life

    Imagine not having to untangle cables or search the entire office for someone who has the same charger as you. What if you could just walk into a room and all of your devices would charge on their own? It sounds unreal, but that technology is exactly what scientists at ITMO are working on right now. They recently revealed a new type of wireless charger – a box that evenly distributes a magnetic field within itself. To charge your device, all you need to do is place it anywhere inside the contraption. That is also what distinguishes it from existing wireless smartphone chargers, which are capable of transferring energy only across short distances. Our latest special project explains how this technology works, why it is completely safe, and whether it can be expanded to cover an entire room. To learn more, follow this link.


  • Alumni Archive: Eleni Bouzouka, Greece

    Once a family, always a family – that is our philosophy! When you become a part of ITMO.Family, you always remain part of it regardless of where you go or what you do. This week, we caught up with one of our alumni from Greece to explore what she has been up to since she graduated with a Master’s degree in physics. Does she miss ITMO? Read on to find out.


  • Next-Gen Wireless Chargers Developed at ITMO

    Researchers from ITMO University have come up with a new kind of wireless chargers – boxes with a uniformly distributed magnetic field inside them. Placing a device anywhere in the box will charge it, which makes the new technology stand out from its competitors, which can only ensure power transfer across short distances. The project will be presented at the second Congress of Young Scientists in Sochi.


  • ITMO Scientists Suggest Cheap Way to Control Optical Signals With Halide Perovskites

    Halide perovskites are a relatively new group of materials that are used in solar cells, diodes, scintillators, and other devices. One of their main advantages is their availability and ease of production. They are also characterized by the stable bound state of an electron and an electron hole that makes up an exciton. By connecting an exciton to light in a photonic crystal plate, the researchers were able to reach record optical nonlinearity values, which makes the plates a promising tool for controlling optical signals and, in the future, can render them useful in optical computers. The article describing the experiment was published in Nano Letters.


  • A Quiet Place: ITMO Physicists Reduce Noise Tenfold With Metamaterial Structure

    Imagine you are in a park in the bustling downtown and there is sunshine, fresh air, and… total quiet. Doesn’t feel real, does it? Researchers from ITMO University have developed a translucent vented structure that decreases noise by up to 20 dB within the spectral range of 2 to 16.5 kHz. This means that it covers 70% of the audible bandwidth. The new structure can be used to build noise-insulating barriers alongside roads or pavilions in parks.


  • Nobel Prize in Physics 2022: What Are Entangled Photons and Why They Are Important?

    This year’s winners of the Nobel Prize in Physics were announced today, and they are Alain Aspect, John F. Clauser, and Anton Zeilinger for "experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science," as stated by the Nobel Committee. ITMO.NEWS talked to Vladimir Egorov, the head of the university’s Laboratory for Quantum Communications, to learn how these experiments impacted quantum computers and what we should expect next in this field.


  • ITMO Researchers Suggest All-Optical Data Processing Method Using Heating

    Metal-organiс frameworks (MOFs) are a new class of compounds that is famous for its unique properties. They have been considered a functional material for gas adsorption, industrial membranes, and catalysts; however, researchers from ITMO have gone further and decided to zone in on MOFs’ optical properties. In a recent paper, they demonstrated that thanks to MOFs’ flexibility, these properties can be changed when subjected to lasers. This new effect can pave the way for all-optical data encoding, transfer, and storage.


  • Traveling at the Speed of Light: What Is Special Relativity?

    In 1915, Albert Einstein’s general theory of relativity famously revolutionized our understanding of gravity. However, it’s a lesser-known fact that special relativity was the precursor of this discovery. In this article, we talk to Georgy Sizykh, a PhD student at ITMO’s Faculty of Physics, about the way the theory of special relativity came to be, how it can help us slow down aging, and what is the connection between space and time.


  • Paving the Way to Next-Gen Devices: Your Guide to Metaphotonics

    It's rare for fields like physics, chemistry, biology, and computer science to function in isolation, most scientific breakthroughs these days involve an interdisciplinary approach. Metaphotonics is one of such field that has the potential to revolutionize traditional views of optical and electronic devices. How? In this article, ITMO’s Sergey Makarov, head of the Laboratory of Hybrid Nanophotonics and Optoelectronics and the frontier laboratory Solution-Processable Laser Diodes, and Ivan Sinev, a researcher at the International Research Center for Nanophotonics and Metamaterials help us discover this nascent field. 


  • Researchers Propose New Multipolar Lattices for Improved Metasurfaces

    Scientists from ITMO University’s Faculty of Physics have predicted a unique type of bound states in the continuum – one that is completely resistant to changes in the system parameters. This would allow researchers to control the resonance properties of metasurfaces and, eventually, to develop more efficient optical and optoelectronic devices of the next generation. The corresponding paper received special recognition from the editors of Physical Review B (Letter) and was published in the section Editor’s Suggestion.
