• We have theoretically and experimentally justified possibility of creating near-field measurement of parameters of nanolayers using low-dimensional resonance systems having maximum sensitivity to nanolayer characteristics and providing an opportunity to measure thickness, electric conductivity and dielectric permeability of nanolayers.
• We have theoretically and experimentally justified methods of producing new functional devices of super high and extremely high frequency based on photon crystals.
• We have theoretically and experimentally justified new technologies of measuring thickness and electric conductivity of nanolayers in quantum-dimensional structures by spectrums of deflection and passage of super high frequency and optical radiation interacting with them.
• Our Laboratory has developed a technology for forming nanocomposites with inclusions in the form of carbon nanotubes with adjustable characteristics in the super high frequency range. We have theoretically and experimentally justified radio technologies for controlling parameters of nanocomposites with inclusions in the form of carbon nanotubes.
• Using near field super high wave microscopy in the autodyne information signal detection mode we have found earlier unknown physical effects occurring in micro- and nanoelctronics.
• Using the near field super high frequency microscopy we have measured distribution of free charge carriers and electric field intensity in semiconductor structures of Gunn diodes. The measurement has been made without contact and with high resolution. As a result we have for the first found possibility of a stationary multi-domain mode in such diodes that allows for an explanation of the physics of their work.
• Our researchers have developed new physical approaches to creating devices for processing electromagnetic signals in the terahertz frequency range based on qualities of plasma oscillations in semiconductor and graphene periodic nanostructures (planar plasmonic crystals).
• Our researchers has shown that utilization of planar plasmonic crystals allows to significantly increase detecting capabilities if THz-plasmonic detectors, to advance into higher frequency and to eliminate usage of additional antennas. Due to small wave length of plasma oscillations and resonance amplification of near field in defected plasmonic crystals it is possible to conduct plasmonic near field THz-microscopy of nanoobjects with submicron resolution.
• Giant amplification and effective laser generation of THz-radiation in planar plasmonic crystal has been found.

Experimental characteristics correlate greatly with calculations.
• We have found hybrid «fast» magnetoelastic waves in film YIG structures.
• In the field of phonon crystals we have achieved new functional possibilities for usage of 1D and 2D phonon crystals that allowed to reach significant increase of quality factor of super high frequency acoustic resonators (up to 11 000 on surface acoustic wave and up to 100 000 on volume acoustic waves).
• Our researchers have created thermally stabilized super high frequency magnetoacoustic resonators adjustable in the band of 5%, super high frequency radio identification tags based on deflecting delay line based on surface acoustic wave in the range between from 2400 to 2483 MHz.

• The Laboratory has developed a new generate of devices for transmitting and processing data functioning in the microwave ranges.
• For the first time we have conducted research reflecting features of propagation of spin waves (spatial and temporal localization, collimation, pumping) in such systems and developed methods to control connection to create controlled devices for processing super high frequency signals in new generation information and telecommunication systems.

Implemented results of research:

• We have conducted R&D work in «Mathematical modeling of processes of propagation of electromagnetic waves in stratified and resistive dielectric film structures and developing a technology for their formation», developed small-dimension coordinated loads on frequency ranges 8,15–12,05 GHz, 12,05–17,44 GHz, 17,44–25,95 GHz, 25,95 GHz–37,50 GHz, 37,50–53,57 GHz, 53,57–78,33 GHz.
• We have conducted R&D work for the Ministry of Industry and Trade of the Russian Federation in «Developing a module for wide-range delay line with electrically controlled delay in the frequency range range of (8–18) GHz».

Education and career development:

• We have published a textbook «Super high frequency photon photons – a new type of periodic structures in radioelectronics» (Authors: D. A. Usanov, S. A. Nikitov, A. V. Skripal, D. V. Ponomaryov).
• 7 candidate dissertations have been defended.

Organizational and structural changes:

• We have created an R&D group in «Magnonic crystals» as well as a unique Brillouin spectroscopy complex (Brillouin Light Scattering, BLS) based on Mandelstam-Brillouin light scattering based on spin waves. Using the BLS complex we will conduct experimental research of spatial dynamics of spin waves in microwave and terahertz ranges.
• We have equipped an ISO 6 cleanroom and a system for vacuum magnetron spraying VSM-100 ADVAVAC Surface Technologies with a set of targets made of various metals including a platinum target produced by K. J. Lesker (USA) and a system for plasma processing (cleaning) ATTO II Diener Electronic GmbH. The equipment will be used for producing planar arrays of ferromagnetic structures with micron and submicron topological norms.
