RESONATING CAVITY DEVICE WITH TRANSVERSAL DIMENSIONAL VARIATION CONVERSION, INDUCED BY A TEMPERATURE VARIATION, IN LONGITUDINAL DIMENSIONAL VARIATION

摘要

a device includes a resonant cavity body (d) waveguide(1) including a side wall extending in a directionwith a first longitudinal coefficient of thermal expansion anddefining a resonant cavity (cr) with a first (2) and (3)the opposing end walls. the first end wall (2) has athe second coefficient of thermal expansion lower than the first strictlythe coefficient and includes an inner face bonded to a first set(e1) which includes a main plate (6) having a thirdcoefficient of thermal expansion, be less than the first, anda transverse dimensions substantially equal to the values.in the lower cavity (cr), and an intermediate element (7).thermal expansion coefficient of a fourth, strictlyhigher than the third, with one part (8) bonded tipat the main plate (6) arranged, when there is a change into convert a temperature of a dimensional changedimensional change in a transverse direction according to the directionlongitudinal longitudinal translation, which leads to the platemain(6) in the cavity (cr).
