Title HIGH-FREQUENCY ELECTROMAGNETIC FIELD MEASUREMENT DEVICE
Abstract [Problem] To provide a high-frequency electromagnetic field measurement device that can separate the impact of a high-frequency electromagnetic field and the impact of a high-frequency electric field, that are generated by the input of a high-frequency signal, and that can measure a high-frequency electromagnetic field with high precision. [Solution] A magnetic force sensor (21) is formed from the cantilever of a magnetic force microscope (11) and can detect a magnetic field. A current line (12) is formed from a coil and is disposed so as to be adjacent to an object of measurement (1). A carrier guide means (13) inputs a high-frequency carrier signal to the object of measurement (1), and a reference wave guide means (14) is configured so as to input a high-frequency reference wave signal to the current line (12). Further, the potential when the carrier signal is input to the object of measurement (1) from the carrier guide means (13) is made to match the potential of the magnetic force sensor (21). The magnetic force microscope (11) has a placement stand (22) onto which the object of measurement (1) is placed, a displacement measurement means (23) for measuring the displacement of the magnetic force sensor (21), and a scanning means (24) for scanning the magnetic force sensor (21).
