Project summary

The goal of the project is the elaboration of a microwave radio-receiving system, and its application in biomedical and applied research.

The system consists of a bifocal antenna system with high-sensitivity radiometric receivers. The object under consideration is placed in one focus of the antenna, and the source of irradiation in the other. The measurement of radiation of local points of the object in different frequencies will make it possible to examine internal processes occurring within the object under investigation.

The planned radio-receiving system is intended for use within a wide spectrum of frequencies (30-140 GHz) The sensitivity of radiometers is ≈0.1 K, at a constant time of 1 second.

During biomedical examination, a narrow beam (the size of the focal spot is approximately the length of the wave of radiation being received), and a wide-band system will make it possible to examine cells and sub-cell formations in the course of their functioning. It is expected that the initiation of various processes in the cell should change both the structures themselves and the interactions between these structures and other components of the nucleus, in which the genetic material of a living organism is concentrated. Structural changes in biologically active substances, interaction with the environment, and initiation of various mechanisms are unconditionally connected to energy changes of both local and integrated organizations within the cell.

Also planned is the investigation of highly inflammable materials, which will make possible the following:


1. To evaluate the thermal characteristics of both separate components and the material as a whole.
2. To reveal the influence of "technological" processes on the thermal properties of a material.
3. To evaluate the energy characteristics of the thermal phenomena occurring in a material.
4. To determine the conditions necessary to preclude unacceptable functioning of the material.

The participants in the project have the experience necessary to ensure its realization. In particular, the participants in the project have published numerous scientific articles.

The following is a list of articles of particular relevance to the elaboration of this project.

With the implementation of this project, the main goal of the ISTC will be realized. Three-quarters of the participants are former "weapons specialists", yet the results of the work will be used for peaceful means.

Foreign collaborators have pledged to promote effective and concentrated activity during the implementation of the project, through information exchange and consultations. The methodology of the project includes theoretical calculations and the collation of experiment and theory.
