Abstract The basic principles of
electromagnetic (EM) techniques for nondestructive
testing (NDT) of dielectric materials are first reviewed in consideration of
the physical phenomena involved in the interaction between the material being
tested and the exploring radiation. Applications and experimental results of
particular nondestructive measuring techniques
based on the use of radio frequency (RF) capacitive and microwave (MW)
resonant sensors are then reported. The aim is to investigate the possibility
of using EM waves in industrial NDT of dielectric materials. The use of these
waves, for such purposes is not yet as common as that of other types of
radiation and many aspects still require investigation. Key Words: Nondestructive testing, permittivity measurements, Electromagnetic
sensors |
