Additive manufacturing of solid diffractive optical elements via near index matching

Reut Kedem Orange, Nadav Opatovski, Dafei Xiao +11

Diffractive optical elements (DOEs) have a wide range of applications in optics and photonics, thanks to their capability to perform complex wavefront shaping in a compact form. Ho…

Generalized torsion for hyperbolic $3$ --manifold groups with arbitrary large rank

Tetsuya Ito, Kimihiko Motegi, Masakazu Teragaito

Let $G$ be a group and $g$ a non-trivial element in $G$ . If some non-empty finite product of conjugates of $g$ equals to the trivial element, then $g$ is called a generalized torsi…
