Abstract: A detection apparatus includes a sample holding section, an irradiation means, a detection means, a calculation means, and an evaluation means. The irradiation means irradiates a substance held in the sample holding section with a THz wave. The detection unit detects a THz wave that has passed through or been reflected from the substance. The calculation unit determines a frequency dependence of a property of the substance with respect to the irradiated THz wave and then calculates a slope of a straight line or a slope of a straight line obtained by straight-line approximation of the frequency dependence of the property of the substance. The evaluation unit evaluates the state change of the substance by comparing a previously-obtained slope of a straight line of the frequency dependence of the property of the substance in a standard state and the slope of the straight line of the substance calculated.

Abstract: An oscillation device has a resonant tunneling diode formed by interposing a gain medium including a first barrier layer, a quantum well layer and a second barrier layer between a first thickness adjusting layer and a second thickness adjusting layer. The oscillation device also has a switch for switching the polarity of a bias voltage being applied to the resonant tunneling diode. The first thickness adjusting layer and the second thickness adjusting layer have different thicknesses. Thus, a single oscillation device is driven to oscillate with different oscillation frequencies.
