2. Expected Results and Their Application
The analysis of the characteristics of multi-port waveguide junctions shows that single inclusions do not allow to reach acceptable level of agreement between waveguide arms and sufficient broadbandness of waveguide junctions. Therefore, for optimization of multi-port waveguide junctions we consider the systems of such inclusions.
Within the frames of the project the following structures will be considered and optimized:
1.Waveguide triplets (WT) with SAI of different types;
2.Open WT (OWT) with SAI of different types;
3.Four-port waveguide couplings (FWC) with SAI of different types;
4.Open FWC (OFWC) with SAI of different types;
5.Multi-port functional devices based on the modern, frequency-selective nano-materials, including the devices, based on photonic crystals of the finite size. [69-75].
Within the framework of the project it will be studied the electrodynamic properties of considering structures, it will be built the graphs of dependence of electrodynamic characteristics on different geometric parameters of the problems, and also the figures of field distribution in neighbor zone. The algorithm for optimization of the geometric and physical parameters of the systems will be worked out for obtaining the best constructions with the properties given beforehand.
2.1. Sustainability Implementation Plan
2.1.1. Results to be promoted
The devices of SHF do not have tuning elements; therefore, their serial production and experimental study must be preceded by their theoretical and machine design of these structures.
The scientific value of the proposed project consists in the development of standardized methods of electrodynamic analysis and optimization of the constructions: irregular multi-port waveguide junctions
with included system of artificial heterogeneities, and also both free and irregular open two-port waveguide branchings.
The commercial significance of the project consists in the creation of competitive production, which will have wide area of potential application in the systems of emission of flight vehicles, radio-electronic and communication systems, antenna – feeders, microwave and fiber-optic technology, SHF integrated circuits, etc.
The economic and social significance of the project consists in the creation of scientific – technical production, which can be used for obtaining concrete products in different spheres of science and technology. Furthermore, scientific theories and packages of programs, obtained as a result of the realization of the project, can be used in the spheres of telecommunications, computer systems and networks, in the training processes of the university programs of corresponding specialties. The project will increase knowledge and habits of young doctoral candidates and student – programmers, it will help them in the independent setting and solution of scientific – technical problems.
2.1.2. Uniqueness of results
The structures considered in the project possess the following advantages: they may unite within themselves the purposes just of several number of functional elements, namely – in the case of closed waveguide structures (WT and FWC with SAI) at the same time they may serve as a filters (rejected and banded), wave types transformers, transitions between the cascades of VIS, power dividers and antenna switchers. While in the case of open structures (OWT and OFWC with SAI) they may be considered as multi-functional antenna-feeder systems, including antennas and filters. Changing the geometric and physical parameters of SAI it is possible easily, quickly and effectively rule the radiation pattern as well, as varying the types and parameters of SAI may be reached the retuning of antenna systems relative to the frequency parameter.
In the work the effective algorithms of solution of the optimization problems of open and closed waveguide structures, utilizing the system of artificial inclusions of different type, will be received. They are based on determination of the extremes of un-traditional generalized aiming functionalities, which may find in future the wide utilization in the applied electrodynamics for solution of the optimization problems.
The advantage of the given algorithm should become its universality probably it may be used for optimization of the waveguide systems through very different integral criteria.

2.1.4. Expected income
Main organization GTU plans to have profit from the results of the project by means of sale of technologies. Participants of the project have adequate experience in preservation of intellectual property and, then, sales of technologies. Participants have required infrastructure and prepared staff to manage with such activities.
