Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for measuring characteristics of an object with an acoustically induced electromagnetic wave capable of irradiating electromagnetic wave with acoustic vibration and being applicable to every object including a human body.SOLUTION: A method and apparatus for measuring characteristics of an object with acoustically induced electromagnetic wave measures a change in the characteristic value or the like of charged particles in an object from an electromagnetic wave induced by irradiating an object to be measured with an acoustic wave. The portion (2) of the object to be measured which is irradiated with an acoustic wave focus beam (1) is in a charge distributed state in which many positive charged particles (3) are present, and thus the electromagnetic waves induced by the positive charged particles (3) and negative charged particles (4) do not completely negate each other to produce an actual electromagnetic wave (6). When the concentration of the positive charged particles (3) and/or the negative charged particles (4) changes, the strength of the electromagnetic wave (6) changes, thus allowing the concentration change in the charged particles to be detected from the strength change in the electromagnetic wave (6).

Abstract: PROBLEM TO BE SOLVED: To provide a small and low power-consumption far-infrared light emitting device which is capable of emitting far-infrared light and has a wavelength variable function. SOLUTION: The far-infrared light emitting device has, on a two-dimensional electron system 4 formed in a solid material such as Si, GaAs, or the like, a disk-like source electrode 5, an annular gate electrode 6 which is formed outside the source electrode 5 and has a cutout 6a in part of the annulus ring, a first gate electrode 7 formed at a given distance away from the cutout 6a outside the gate electrode 6, and a drain electrode 8 formed further outside the first gate electrode 7. The far-infrared light emitting device 1 is made into a quantum hall state of a Landau level filling rate of 4. By applying voltage to the first gate electrode 7 to set a Landau level filling rate below the first gate electrode 7 to 2 and by adjusting a potential difference between the source electrode 5 and the drain electrode 8, a difference in energy between a lower Landau level 9a and an upper Landau level 9b is made to become a chemical potential difference the same as or above Landau level energy (cyclotron energy).
