Project summary

The objective of the Project is the system analysis of electro-magnetic properties of both free multi-port wave-guide junctions and junctions with artificial heterogeneities and creation of a program set for optimization of parameters of such junctions aiming improvement of their coordinating properties.

The topicality of the Project objectives is conditioned by the modern trends of development of radio-electronic and communication systems which give increased requirements to the efficiency and electro-magnetic combination of both full systems and their constructive, transmitting and transforming elements. In not less degree these requirements relate to the multi-port wave-guide junctions and branches compiling the element base of various radio-electronic and communication systems of super high frequencies (SHF).

By that the task of acceptable level of coordination of the multi-port wave-guide junctions in the wide frequency field cannot be solved without putting in constructive changes in geometry of junctions. Such constructive changes can be input of junctions of artificial heterogeneities into the construction.

Due to the expense of experimental investigation of optimal sizes and material characteristics of constructions of the multi-port wave-guide junctions with improved coordinating properties, phase of their serial issue must precede the phase of their electro-dynamic analysis and multi-parameter investigation.

For implementation of the Project objectives will be used a strict theoretical approach using Fourier technique of transformations, theory of residuum, generalized functions, methods mirror images, partial areas, moments with attraction of the method for generalized matrixes of dispersion and original methods for transformation of multi-polar spectrum in spectral (modal) one.

By that the Project participants possess all the necessary data for the successful solution to the task of the Project which is the natural continuation of the above-mentioned ISTC Project G-871.
