Abstract
The device serves for changing the length of a running path of an electromagnetic wave. It comprises a wave guide which is wound onto a core. The core is formed in two parts, wherein the distance of the core parts to one another is changeable in order to extend the wave length in a defined manner.
Claims14
A device for changing the length of the running path of an electromagnetic wave, comprising a wave guide in which the electromagnetic wave is led and a multi-part core consisting of two core parts on which the wave guide is wound, the length change of the wave guide being effected by extension of the wave guide wound on the core in that a change in position of the core parts to one another is effected, wherein the wave guide in sections is led essentially in a straight line and that the extension is effected essentially only in these straight-lined sections of the wave guide, and at least one piezoelement is arranged between the core parts and operated in the resonance region for producing the position change.
