The physicists from ITMO University, Ioffe Institute and the Australian National University examined a new mechanism of realization of high-quality optical resonators. It is based on the mutual destructive interference of two low-quality optical states in one resonator allowing for secure “trapping” of light in various materials even at small scales. The theoretical results of…
Physicists Designed New Antenna for Supersensitive Magnetometers of a New Generation
Scientists from ITMO University and Lebedev Physical Institute of the Russian Academy of Sciences proposed a new microwave antenna that creates a uniform magnetic field in large volume. It is capable for uniform and coherent addressing of the electronic spins of an ensemble of nanodiamond structure defects. This can be used to create super-sensitive magnetic…
Researchers Propose High-Efficiency Wireless Power Transfer System
Today, wireless power transfer (WPT) systems enable to charge electronic devices without plugging them into the wall, but rather by placing them on a special charging pad. However, the transfer distance and efficiency of such systems fall short of market expectations. In a new study, a group of scientists from ITMO University and Giricond Research…
