Millimeter wave technique for material quality characterization
Keywords:millimeter waves, material quality, characterization.
AbstractMillimeter wave bridge technique for non-destructive material quality characterization is described. The idea of this technique is the local excitation of the millimeter waves in the testing material and the measurement of the transmitted or reflected wave amplitude and phase in different places of it, i.e. the material plate is scanned by the millimeter waves beam. Some measurement results of the mechanically non-homogeneous samples are presented.
