Special Issue Information

Dear Colleagues,

The development of modern science and technology is based, among other things, on the design, production and in-depth understanding of advanced materials, technologies and electromagnetic processes. This engineering basis should be constantly improved upon as global problems persist everyday in strategic industries such as the environmental, energy, medical, specialized electronics, emission-free automotive and arms industries. Techniques and technologies pertaining to cold atmospheric plasma, superconducting, renewable energy sources and functional materials, as well as biomedical, mechatronic and space nanotechnologies allow us to solve these problems, to a significant extent.

Therefore, this Special Issue focuses on the theory of, research on and search for practical applications of electromagnetic materials, processes and phenomena in the Environmental Protection and Energy sectors.

Issues of interest for publication include, but are not limited to, the following:

  • Plasma and ozone technologies for the treatment of air, water, soil, crop and pest control; syngas production; and biofuel production;
  • Energy-saving superconducting devices (cables, magnets, fault current limiter SFCLs, magnetic energy storage SMESs, transformers, bearings, machines and SQUIDs) and their applications;
  • Electromagnetic technologies in the agriculture and food industry;
  • All aspects of electromagnetic compatibility, the influence of electromagnetic fields, noise and vibration on living organisms, and environment monitoring;
  • Renewable energy generation and storage facilities, quality, monitoring, consumption and management aspects for green energy;
  • The computer-aided design of electromagnetic devices and processes;
  • Novel micro- and macro-materials, electromagnetic materials and properties, dielectrics, ferroelectrics, and their applicability in environment protection and energy technologies;
  • Biomedical, mechatronic, robotic and space technologies for the energy sector;
  • Advanced nanotechnologies and nanomaterials that rely on electromagnetic phenomena and their properties, energy-effective nanostructures, nanofluids for heat and energy applications, and functional materials.

This paper describes selected results of the design and optimization of an electromagnetic field concentrator (MFC) for process chambers. On the basis of 2D/3D FE analysis, it was confirmed that the presented new structure for an electromagnetic field concentrator with three-phase windings and an additional DC central coil excites, in the working space of the device, a steady or time-varying magnetic field with adjustable peak value, pulsation amplitude and vector magnetic field orientation. The presented field concentrator can be used for process chambers carrying out chemical, biological, thermal and measurement processes, among others. Full article

As electromobility and especially the electrification of public transportation develops, it is necessary to safeguard human health and minimize environmental impact. Electromagnetic fields generated by the current flowing through on-board batteries, installations, converters, propulsion, air conditioning, heating, lighting, or wireless communication systems in these vehicles may pose risks to drivers and passengers. This research investigates electromagnetic fields induced by extreme low-frequency currents and permanent magnets on electric and trolleybuses implanted in Lublin, Poland. The identification of electromagnetic fields concerned an electric bus model and two trolleybus models. A comparative analysis of the results obtained with the permissible limits in the environment was carried out. Full article

This paper presents the influence of superconducting tape insulation on the recovery time of superconducting fault current limiters. The analysis is based on the experimental results of short-circuit tests. The reduction in the thermal and dynamic effects of the passage of a fault current can be achieved by limiting the short-circuit time and the value of the surge current. An ideal fault current limiter is required to have almost zero impedance at operating currents and significant impedance at fault conditions. A superconducting fault current limiter (SFCL) meets these requirements under certain conditions. The recovery time—a very important parameter—shows the ability of the limiter to return to the superconducting state to be ready to limit the subsequent short circuit. The experimental results show that the recovery time can be significantly reduced with the application of thin-film insulation and an appropriate design of the conduction cooling of the HTS tape.

Title: Effect of plasma gas type on the operation characteristics of a three-phase plasma reactor with gliding arc discharge

Abstract: Three-phase gliding arc discharge reactors are devices in which it is difficult to maintain stable plasma parameters, both electrically, physically and chemically. The main cause of plasma instability is its source, which is freely burning arcs in a three-phase system. In addition, these arcs burn at low currents and are intensively cooled, further increasing their instability. These instabilities translate into the electrical characteristics of the plasma reactor. The analysis for the three gases nitrogen, argon and helium shows that the type of plasma-generating gas and its physical parameters have a strong influence on the operational characteristics of the plasma reactor. Current-voltage characteristics, power and efficiency characteristics of the plasma reactor, as well as characteristics of harmonic content in current and voltage of arcs were plotted experimentally. Characteristics obtained in this way make it possible to determine the areas of effective operation of the plasma reactor and to estimate the quality of the generated plasma.
