Abstract
The research program "Applied Electromagnetics" in its broader sense comprises theoretical and practical research of electromagnetic phenomena inside material and outside of it. More particularly, it is connected with problems of electromagnetic conversion in real conditions, which are reflected in technical, acoustical and voltage phenomena, and with researching of electromagnetic phenomena in insulating and grounding systems as well as in biological tissues.
Within the framework of the research program, parallel work is carried out on three fields, with the ultimate aim to incorporate all the knowledge in a complex system which will as accurately as possible cover all demands of a real electromagnetic problem. The three fields are:
- research and development of mathematical models for defining magnetic, electrical, current and temperature field in stationary and dynamic conditions,
- development of measurement methods for defining real characteristics of material,
- development of models used by solving the inverse problems in electrotehnics.
The first part focuses on numerical methods for electromagnetic field calculation, namely finite element method and boundary element method. The development and application of the above methods are directed to CAD program solutions on concrete objects. In most cases, these objects are electromechanic converters, actuators, switches, insulating and grounding systems, etc. In technological fields we develop optimization methods with all necessary attributes.
The development of measurement methods focuses on measurement methods for accurate defining of real characteristics of materials and losses in them, which is necessary for a more real mathematical model of electromagnetic system. The work is carried out on methods for defining magnetization and hysteresis curves, on determination of pulsating and rotational losses in magnetic materials, on software development for support of measurement methods and on production of measurement yokes for different shapes of measurement samples.
By solving the inverse problem we have decided for a special variant of boundary element method, the so-called DRM method, which enables a simple dealing with the domain, which we want to determine by the inverse problem. Our initial work has been directed to problems of 2D static fields, where we detect unknown distribution of electromagnetic field sources, or rather, unknown material property. Both problems are very actual in bioelectromedicine, by searching defects in material structure, by development of measurement methods, etc.
Significance for science
The field of applied electromagnetics is a reality in the world and for many segments still an open issue. Research needs to continue within areas such as: ? research into magnetic fluids in the senses of characterisation, modelling, and their behaviour within a magnetic field, together with searching for new areas for their usage. The usefulness of magnetic fluids is already very widespread, for example, they are used in medicine, for the nondestructive testing of materials, for measuring sensors, etc. Magnetic fluids also openup new research areas where new opportunities can be envisaged for their use. ? research into new magnetic materials for electromagnetic transducers and design solutions adopted for their use in the sense of increasing the transducer’s capacity and efficiency, of developing special electromechanical transducers for use in electric and hybrid vehicles. ? research into dynamic models for soil ionisation at very fast atmospheric discharges into the soil, research of the impact of electromagnetic fields in these cases and the development of adequate protection for electric power facilities and other buildings. The research work and expected scientific and applicative results of the programme group regarding these areas will in any case be a step forward in the development of science, not only in the domestic but also in the wider global arena. All research results will also be published both at conferences and in publications of various kinds and levels, with particular emphasis on the journals with JCR. This orientation of the programme group is confirmed by the results from the past. Over the period of the current programme since 2009 we have published 124 articles which are according to COBIS categorised as “1.01 Original research papers”, of which 75 papers have been published in journals with an impact factor (JCR) and 15 in journals with JCR in the first quarter (1). We have made 168 contributions at international conferences. We have confirmed our scientificresearch and professional work through contacts with recognised scientists and researchers, and through contacts with their laboratories. These contacts have allowed the spreading of our knowledge throughout a wider global sphere. Our participation in international projects has also enabled a concrete twoway transfer of knowledge between institutions. The importance and contribution of the programme can also be seen through the organisations of international meetings. In 2016 we will organise the wellestablished EHE International Conference (6th International Conference on Electromagnetic Fields, Health and Environment).
Significance for the country
Research within the context of the planned programme will contribute to an increase in the competitiveness of the Slovenian electrical industry thus allowing the production of products with higher addedvalue. Research into the aforementioned areas is absolutely necessary for the Slovenian electrical industry because our industry is a high quality industry and is highly export oriented. If Slovenian industry wants to stay competitive within the global economy it must absorb more knowledge and this knowledge must be used for innovative production processes. Therefore, the basic objective of the applied electromagnetics research programme is to produce useful knowledge as far as possible and to transfer this knowledge from its laboratories into industry. This programme to date has been successful regarding knowledge production and transfer. However, such production can only be enabled on a solid foundation of basic research. Therefore the important part of the programme is the planning for fundamental research. This fundamental research is then further linked to applicative and development projects. Our results are especially useful for industry within the following areas: ?Electric motors, electromechanical converters ?Switching technology, power systems ?Measurement techniques, research of electrical materials ?Electrical household appliances ?Use and development of magnetic fluids ?Electromechanical converters in the automobile industry for electric and hybrid vehicles, vessels and small power generation systems, ?the reduction of energy usage and increased production and export of energy highefficient products ?Construction and development of new lightning protections and grounding systems ?Protection against the effects of electromagnetic fields on the environment
