  • Apparatus for non-destructive testing of dielectric/magnetic materials
    Patent number: 5389875
    Abstract: A dielectric probe, of the type in which an electromagnetic wave is reflected from a dielectric/magnetic structure and spectrum analyzed, further includes a coil for applying a magnetic field to the structure as the wave is being reflected. Information about the intrinsic electromagnetic properties, integrity and structure of the material is obtained by comparing the reflected spectra for both the magnetic field on and off conditions.
