Abstract :
The paper proposes an electromagnetic coupling device which improves the incidence efficiency of electro-magnetic wave into the inspected objects when an electromagnetic wave (radar) is used for non-destructive inspection. The device enables a fast non-destructive inspection by a radar which is attached to the bottom of an inspection vehicle. That is, it enables the radar to run fast with a lift-off to the inspected objects. As the inspected objects we have railways and roads in mind and consider to detect cavities under the track and the ground.
