The present paper considers an optimal electromagnetic coupling device which improves the incidence efficiency of electromagnetic wave into the inspected objects when an electromagnetic wave radar is used for non-destructive inspection. Concretely, the paper proposes a moist multi-string type coupling device attached to the bottom of the radar. The coupling device enables the radar move fast over the inspected object without causing any damage to the radar, and consequently realizes a fast and reliable non-destructive inspection of anomalies in inspected objects.
