CHARACTERISTICS MEASUREMENT DEVICE FOR OBJECT TO BE MEASURED AND CHARACTERISTICS MEASUREMENT METHOD FOR OBJECT TO BE MEASURED

A characteristics measurement device for an object according to the invention comprises a sound wave generator that emits a sound wave; a receiver that receives from the object an electromagnetic field generated by the sound wave being irradiated to the object; a sound wave medium between the sound wave generator and the object the electromagnetic field separated from a reverberating electromagnetic field caused by reverberating vibrations of the sound wave generator in time; an inverse diffuse that inversely diffuses the electromagnetic field received by the receiver using a reference signal associated with the sound wave; and a measurement unit that extracts at least one characteristic selected from a group consisting of electrical characteristics, magnetic characteristics, electromechanical characteristics and magnetomechanical characteristics of the object based on at least one measurement selected from a group consisting of intensity, phase and frequency of the inversely diffused electromagnetic field.
