1-10. (canceled)
A waveguide element for guiding an electromagnetic wave, the element comprising:
- a cavity surrounded by an electrically conductive material;
- wherein the cavity has a cross-section perpendicular to a propagation direction of the electromagnetic wave, the cross-section having an alternating regular structure along a virtual line in a plane of the cross-section.
A radiofrequency arrangement, comprising:
- a waveguide element for guiding an electromagnetic wave, the element including:
- a cavity surrounded by an electrically conductive material,
- wherein the cavity has a cross-section perpendicular to a propagation direction of the electromagnetic wave, the cross-section having an alternating regular structure along a virtual line in a plane of the cross-section;
- and
- a radiofrequency circuit coupled to the waveguide element.
