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.
