Professors from Russia and Israel written a monograph on radio waves

13 March 2019

Vladimir Yakubov, a professor at the TSU Faculty of Radiophysics, and Nathan Blaunstein, a professor at the Jerusalem College of Technology (Israel) and a graduate of TSU, have published “Electromagnetic and Acoustic Wave Tomography”, a monograph in English. They described the development of radiowave tomography methods and demonstrated how they can be used to ensure safety in crowded places, for nondestructive quality control, and for diagnosis of diseases.

- The monograph is a collection of articles on the development of radiowave tomography methods as a means of remote nondestructive testing, diagnosing the internal structure of translucent media, and reconstructing forms of opaque objects based on multi-angle sensing, - said Professor Vladimir Yakubov. - We described physical and mathematical models designed to recover images of hidden objects based on tomographic processing of multi-angle remote measurements of the scattered radiation of radio and acoustic (ultrasonic) waves.

The team of Tomsk radiophysicists is creating devices that in practice demonstrate the effectiveness of the methods described. For example, similar devices are useful for safety. So, Radio Eyes-Anti-Terror is designed to recognize hidden electronic objects - radioelectronicelements containing diodes, circuits, and starters. Radiowatch can determine the number of living people behind an obstacle, for example, behind a wall, and the trajectory of their movement and even breathing.

In addition, radiowave tomography can be used to create a comfortable urban environment. For example, it can be used to identify irregularities (stones and impurities) in concrete or asphalt and to improve the quality of coatings, for use as “eyes and ears” in unmanned vehicles, and for other purposes.

Also, devices based on this method can be used in medicine in the diagnosis and control of various diseases, such as breast cancer, and determining blood sugar levels.
