Abstract
The resonator comprises a shell 1 a having a pole 2 held by a support rod 3, the shell having an annular edge 4 defined by an inside surface 5 and an outside surface 6 that are geometrically similar and that extend around a common axis of revolution R, the inside surface and the outside surface being offset relative to each other along the axis of revolution in such a manner that the shell presents a thickness E along the annular edge 4 that is greater than the thickness e that it presents in the vicinity of the pole 2.
Claims2
A resonator, comprising:
- a shell (1);
- said shell having a pole (2);
- said pole being held by a support rod (3);
- the shell (1) having an annular edge (4) defined by an inside surface (5) and an outside surface (6) that are substantially hemispheres and that extend around a common axis of revolution (R);
- wherein a center (C1) of the inside surface (5) and a center (C2) of the outside surface (6) are offset relative to each other along the axis of revolution (5) with a predetermined distance (d) between the centers (C1, C2);
- and
- wherein a radius (R1) of the inside surface (5) is different from a radius (R2) of the outside surface (6) in such a manner that the shell presents thickness (E) along the annular edge (4) that is greater than the thickness (e) that the shell presents in the vicinity of the pole.
