Abstract:
1. An electromagnetic wave measurement device comprising: an electromagnetic wave outputter that outputs an electromagnetic wave having a frequency equal to or more than 0.01 THz and equal to or less than 100 THz toward a device under test; an electromagnetic wave detector that detects the electromagnetic wave which has transmitted through the device under test; a relative position changer that changes a relative position of an intersection of an optical path of the electromagnetic wave transmitting through the device under test and the device under test, with respect to the device under test, so that the intersection is at a predetermined relative position due to the refraction of the electromagnetic wave by the device under test; and a characteristic value deriver that derives a characteristic value of the electromagnetic wave based on a detection result of the electromagnetic wave detector, the characteristic value being associated with the predetermined relative position, wherein the relative position changer changes the relative position of the intersection of the optical path of the electromagnetic wave refracted by the device under test, and the device under test to coincide with the predetermined relative position.
