Abstract
Provided is an element that can reduce a parasitic oscillation. An element used for an oscillation or a detection of a terahertz wave includes a resonance unitincluding a first conductor, a second conductor, a dielectricarranged between the first conductor and the second conductor, a first negative resistance elementand a second negative resistance elementmutually connected in parallel between the first conductor and the second conductor, a bias circuitthat supplies a bias voltage to each of the first negative resistance element and the second negative resistance element, and a linethat connects the bias circuit to the resonance unit, and the element is configured in a manner that a mutual injection locking in a positive phase between the first negative resistance element and the second negative resistance element is unstable, and a mutual injection locking in a reversed phase between the first negative resistance element and the second negative resistance element becomes stable.
