Abstract
The present invention provides a mode conversion reflector provided on an edge surface of an elastic medium, capable of mode-converting an incident ultrasonic wave with high efficiency and simultaneously reflecting the wave in a desired direction. The mode conversion reflector according to the embodiment includes an elastic medium; and a reflective layer formed of a non-planar structure on an edge surface of the elastic medium, in which an interference phenomenon caused by diffraction of wave occurs by the reflective layer, so that an ultrasonic wave incident through the elastic medium is mode-converted and reflected in a predetermined direction.
