Electromagnetics

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.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Magnetochemistry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
