Development of Methods and Facilities for Radio-Wave UHF Diagnostics of Plane-layered Dielectric Structures

摘要

This report results from a contract tasking Karpenko Physico- mechanical Institute as follows: This project will propose a new approach to the creation of the up-to-date technology for non-destructive testing and diagnostics of plane-layered dielectric materials. The approach is based on the following: (1) employment of the electromagnetic UHF sounding for the plane- layered structures; (2) measuring of the complex reflection coefficient by the different frequencies; (3) theoretical estimation of the reflection coefficient by these frequencies; and (4) employment of the methods of inverse problems' solutions for estimation of the unknown parameters of plane-layered structures using the experimental and theoretical results. Based on this approach a non- destructive testing system will be proposed that has the ability to operate as a defectoscopic, defectometric, and diagnostic system, which also does not imply strong restrictions on electro-physical and geometrical parameters of the plane layers.
