This paper describes some of the latest features in the commercial electromagnetic software Feko (including WinProp). These include the modeling of non-ideal cable shield connections, the parallel direct adaptive cross approximation (ACA) solver, edge and wedge diffraction for the ray launching geometrical optics (RL-GO) solver, and several new features related to automotive radar.

Introduction. Nowadays osteopathy is an offi cial medical specialty. Many years of experience accumulated by osteopathic physicians in our country have proven its effectiveness. The analysis of research papers of those countries where osteopathy is widely used allows to draw the following conclusion: osteopathy is one of the least dangerous therapeutic methods provided that patients deal with well-trained and certifi ed specialists who work in the frame of possibilities of osteopathy. Due to the intensive development of this specialty in Russia it is necessary to provide scientifi c justifi cation to organizational and methodological approaches aimed at ensuring effective and high-quality osteopathic care to the population.Goal of research - to develop proposals in order to improve the quality and effectiveness of osteopathic care provision for the population, taking into account the current situation in health care.Materials and methods. Authors used the following research methods: historical and medico-organizational analysis, literary data analysis, content analysis as well as methods of descriptive statistics.Results. The research presents characteristics of clinics declaring osteopathic care provision, as well as qualities of osteopathic physicians. It also describes patients seeking osteopathic care, and sources of information they use.Conclusion. Authors propose a number of measures aimed at improving the availability and effectiveness of osteopathic care for patients such as training of doctors, creating of regulatory documents, developing quality criteria for osteopathic care provision and popularization of osteopathy among patients.

Subject. The article explores the economic component of sustainable development through the classification of industries from the perspective of assigning the output goods to fixed or current assets, using different types of resources and assessing their condition. It considers factors of production affecting the achievement of the result and determining the development of economic systems at the meso- and micro-hierarchical level. Objectives. The aim is to assess the function of economic systems of different hierarchical levels on the tool-making facilities case. Methods. We apply an approach using general and special methods of comparative and statistical analysis, synthesis and analogies. Results. The paper analyzes the development of the Russian tool-making industry on the basis of resource-oriented approach to assess the functioning of economic systems at various levels. We review interrelations between resource use efficiency, types of sustainable development of economic systems at various hierarchical levels and strategic security of the country. Conclusions. Any development can be considered sustainable, if there is an increment in the intensive development of economic systems at all three levels.

This chapter examines solutions to the Maxwell equations in a vacuum: monochromatic plane waves and their polarizations, plane waves, and the motion of a charge in the field of a wave (which is the principle upon which particle detection is based). A plane wave is a solution of the vacuum Maxwell equations which depends on only one of the Cartesian spatial coordinates. The monochromatic plane waves form a basis (in the sense of distributions, because they are not square-integrable) in which any solution of the vacuum Maxwell equations can be expanded. The chapter concludes by giving the conditions for the geometrical optics limit. It also establishes the connection between electromagnetic waves and the kinematic description of light discussed in Book 1.
