  It is well-known that electromagnetic radiation propagates along a straight
line, but this common sense was broken by the artificial curved light - Airy
beam. In this paper, we demonstrate a new type of curved light beam besides
Airy beam, so called photonic hook. This photonic hook is a curved
high-intensity focus by a dielectric trapezoid particle illuminated by a plane
wave. The difference of the phase velocity and the interference of the waves
inside the particle cause the phenomenon of focus bending.
