  Sept 2014 - Nov 2016

  Research Assistant

  • Created program in C++ for studying of the optical properties of plasmonic crystals. Implemented RCWA algorithm based on spatial Fourier transform for periodic structures. This program helped to analyze physical properties of Fabry-Perot plasmonic crystal• Discovered and described new type of plasmonic mode that emerges when the walls of Fabry-Perot structure are thinner than 10 nm (thin wall mode)• Developed the concept of the ultrasensitive vector magneto-optical sensor, which allows to measure all three components of the external magnetic field simultaneously• Assembled experimental setup for proving the concept of magnetic sensor capable of measuring magnetic fields of 100 fT• Performed analytical calculations to describe physical principles of proposed ultrasensitive magnetic sensor; the results were published in Applied Physics Letters scientific journal in 2016• Developed the concept of light modulation in magnetoplasmonic crystals by excitation of rotational magnetization mode. Used longitudinal magnetophotonic intensity effect to create modulation. Achieved modulation of light equals to 10% by creating rotating magnetic field equals to 10 Oe Show less
