Special Issue Information

Dear Colleagues,

This Special Issue is devoted to the study of the interaction of electromagnetic radiation with materials containing ferro- and ferrimagnets and the use of these materials for the purpose of protection from exposure to electromagnetic radiation of the radio frequency range. Research and development in this area require solving problems related to understanding the physical mechanisms of the interaction of magnets with radio frequency radiation, the technology of composite materials containing ferro- and ferrimagnets, methods for measuring the transmission and reflection coefficients of electromagnetic waves with these materials, and analyzing the structure and chemical composition of the studied samples. The choice of topics is due, inter alia, to the problem of the growing level of electromagnetic pollution of residential areas, which requires the development and creation of new low-cost radio-absorbing materials, as well as the need for a correct assessment of the functional characteristics of the materials being created. Thus, the following main topics are proposed as part of this Special Issue:

1. Physical effects of the interaction of electromagnetic radiation of the radio frequency range with magnetic composites.
2. Chemical technology for the creation of radio-absorbing materials based on ferro- and ferrimagnets, including the following:
  • Sol–gel synthesis;
  • Solvothermal synthesis;
  • Chemical coprecipitation;
  • Polymer technology;
  • Low-temperature ceramic technology;
  • Other synthesis methods.
3. Laboratory methods for measuring the transmission and reflection coefficients of an electromagnetic wave by magnetic composites, including the following:
  • Coaxial transmission line method;
  • Coplanar waveguide method;
  • Transmission line method with horn antennas;
  • Rectangular waveguide method;
  • Resonator method;
  • Watt-metric method;
  • Other measurement methods.
4. Analysis of the structure and chemical composition of magnetic composites, including the following:
  • X-ray diffraction
  • Electron diffraction;
  • Neutron diffraction;
  • Mössbauer spectroscopy;
  • Magnetic granulometry;
  • Electron microscopy;
  • Scanning probe microscopy;
  • Other methods of analysis of structure and composition.
5. Modeling of magnetic composites, including the following:
  • Modeling by numerical methods;
  • Mathematical modeling using theoretical models.
6. Other aspects of the development and creation of magnetic composites for electromagnetic safety.

The article describes the interaction of nanocomposites based on the FemOn–SiO2 system with an electromagnetic field (radiation) in an ultra-wide frequency range 0–1021 Hz. The development of the technique based on the sol–gel method for producing nanocomposites is described, which made it possible to achieve superparamagnetic properties in combination with low toxicity when used in vivo and in vitro and a high microwave absorption coefficient, which makes it possible to use the obtained nanocomposites in solving a wide range of practical problems. The most effective methods of exposure and threshold levels of the electromagnetic field, the corresponding modifications of the magnetic structure, crystalline structure and microstructure of nanocomposites are determined.
