The invention relates to an anti-resonance ele-ment preform for producing an anti-resonant hollow-core fiber, in an axial top view comprising a circular first cir-cle element with a first circle radius and a circular arc-shaped first circular arc element with a first circular arc radius. Furthermore, the invention relates to a method for producing an anti resonance element preform, a preform for producing an anti-resonant hollow-core fiber comprising at least one anti-resonance element preform and an anti-resonant hol-low-core fiber. According to the invention, it is provided that the first circle element and the first circular arc element are connected to one another at two contact points.
An anti-resonance element preform for producing an anti-resonant hollow-core fiber, in an axial top view comprising a circular first circle element with a first circle radius, a circular second circle with a second circle radius different from the first circle radius, and a circular arc-shaped first circular arc element with a first circular arc radius,
An anti-resonant hollow-core fiber, in axial top view comprising a cladding region and at least one anti-resonance element arranged in the cladding region, comprising a circular first circle structure with a first circle structure radius a circular second circular element with a second circle radius different from the first circle radius, and a circular arc-shaped first circular arc structure with a first circular arc structure radius,
