5. The shear panel according to claim 1, wherein, when the secondary coil is fastened to the receiving area of the shear panel, the shear panel replacing a component of the secondary coil having functional characteristics and assuming said functional characteristics.

6. The shear panel according to claim 5, wherein the receiving area is situated in an identical plane as other areas of the shear panel adjoining the receiving area and surrounding the latter.

7. The shear panel according to claim 5, wherein the receiving area is situated in a different plane than other areas of the shear panel adjoining the receiving area and surrounding the latter, the plane of the receiving area being arranged at a predefined distance from the plane of the other areas of the shear panel adjoining the receiving area and surrounding the latter.

8. The shear panel according to claim 5, wherein the functional characteristics of the component of the secondary coil that is replaced by the shear panel is a field-guiding function to thereby influence the total impedance of the resonant circuit in a desirable manner.

9. The shear panel according to claim 1, wherein the predefined distance between the plane of the receiving area and the plane of the surrounding areas corresponds maximally to the height of the secondary coil.

10. The shear panel according to claim 9, wherein the predefined distance is between 25% and 100% of the height of the secondary coil.

11. The shear panel according to claim 10, wherein the angle (α

) of the transition section is smaller in the direction of a coil axis/axis of vibration than transversely thereto.

12. The shear panel according to claim 11, wherein the shear panel is formed of aluminum.
