Spin-electromagnetic waves spectra in multiferroic heterostructures

This work devotes to the theoretical investigations of spin-electromagnetic waves (SEW) propagating in a thin-film multiferroic structures that were composed of a slot-line and structures with several ferrite films. In contrast to earlier works, the spin-electromagnetic waves in the investigated structures are originated from two different electrodynamics coupling. The first one is coupling of the electromagnetic wave localized mainly in the slot-line with the spin wave excited mostly in the ferrite film. The second one is coupling of two spin waves in the different ferrite films separated by a thin ferroelectric film. For theoretical analysis of SEWs propagation in such kind of structures theories of their eigen-wave spectra were developed. Spectra of SEW in the investigated structures were calculated and analyzed. The range of electric and magnetic tunability of dispersion characteristic were investigated. Spectra of SEW in the investigated multiferroic structures are used for investigation of transfer function of periodic structures.

Development of Imatra`s logistics hub as a part of Nordic region

This thesis is dedicated to enhancement and development of Imatra`s logistics potential in order to increase its key parameters and improve the efficiency of the region. To find out the most promising logistics projects was proposed a tool “integral-matrix analysis” which enables to make the priority among the list of proposed projects. Description and functionality of the tool are explained in detail. As a result of analysis, the list of priority projects for the development of the region is presented. Project with the greatest potential is implemented in the thesis work. In conclusion, recommendations for the further development of economic potential of the region are given. The thesis is basically focused on literature review, overlook of secondary and primary data (including the results of the interviews, which were carried out among companies that represent the logistics market). Primary data was collected in interviews with the representatives of the companies, who regularly use logistics services. Total effects that make various Russian regions and companies on the Finnish logistics is summed up and discussed.
