Strategy for Scientific and Technological Development Priority Level: а

Goals and objectives

Research directions: Frequency correlations of deflection and passage rates of super high frequency radiation, surface and volume acoustic waves in one-dimension and two-dimension phonon and phonon-magnon crystals, developing technologies for creating 1D and 2D phonon crystals and super high frequency high frequency acoustoelectronic devices based on them, interaction between terahertz electromagnetic radiation with electron-hole plasma in semiconductor and metallic nanostructures of complex shapes, magnonic crystals, ferromagnetic stratified structures on metallic and semiconductor substrates

Project objective: Theoretical and experimental research of wave processes occurring in metamaterials, research of methods of creating metamaterials and developing devices based on them for applications in radioelectronics and photonics

The practical value of the study

  • 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.
  • We have developed a quazi-field method to calculate interdigital transducers of surface acoustic wave with arbitrary shapes of electrodes that will be used in implementing the project for computing electric characteristics and topology of complex structure interdigital transducers for excitation signals of surface acoustic wave and receiving surface acoustic wave scattered in uncertainty.
  • We have developed a method for computing scattering of surface acoustic waves by a one-dimensional system of surface inhomogeneities using the finite elements method implemented using the Comsol Multyphysics system.
  • Our researchers have studied characteristics of passage, deflection and scattering of surface acoustic wave in one-dimensional systems of surface inhomogeneities.
  • The Laboratory has calculated deflective delay lines accounting for scattering in the volume and produced them for radio frequency identification marks based on surface acoustic wave in «900 MHz, «2.45 GHz» and for the first time in the world «6 GHz» ranges with minimal element of metalized structure 150 nm. 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.
  • We have accumulated theoretical data showing possibility of creating devices based in surface acoustic wave in the range of up to 10 GHz, apodized volume acoustic wave converters with frequencies of up to 40 GHz as well as new functional devices based on surface acoustic wave and volume acoustic wave using «metasurfaces».
  • The Laboratory has conducted complex research of features of propagation of spin-wave excitations in irregular, connected, periodic and multi-layer ferromagnetic structures. 
  • We have produced and certified prototypes of thin-film micro- and nanostructures, conducted theoretical and experimental research of their qualities characterizing features of propagation of spin waves, developed mock-ups of spatially-distributed systems for parallel processing of data in temporal and spatial regions for microwave ranges.
  • 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.

Other results:

  • Three employees of the Laboratory have received the Government of Moscow Award in science and technology for young scientists in radioelectronics.
  • In 2014 we conducted the first conference in Brillouin spectroscopy that later began a periodic international event.
