Bessel functions, central to many problems in mathematical physics, provide solutions to differential equations that describe wave propagation, heat conduction and vibrations in cylindrical or ...

Bessel beams are of great interest due to their unique non-diffractive properties. Using a conical prism or an objective paired with an annular aperture are two typical approaches for generating ...

A Gaussian beam is transformed into a Bessel beam using a binary axicon and then reshaped by a flat multilevel diffractive lens into a micron-sized optical bottle beam, enabling long-distance ...

Bessel Beams are impossible to create, can’t be destroyed, and don’t diffract. In other words, physics has discovered yet another thing that makes no sense. Bessel beams bear the name of Friedrich ...
