Аннотация

During last 2 years it was shown that an electromagnetic field can be made to curve after propagation through a simple dielectric material of special shape, which adds a new-found degree of simplicity. This effect was termed 'photonic hooks' - it is an unique electromagnetic beam configuration behind a mesoscale dielectric particle with a broken symmetry and differ from Airy-family beams. PH features the radius of curvature, which is about 2 times smaller than the electromagnetic wavelength - this is the smallest curvature radius of electromagnetic waves ever reported. The nature of a photonic hook is in dispersion of the phase velocity of the waves inside of particle, resulting in interference. Here, we report a new dielectric particle-based strategy to design self-bending subwavelength structured light beams.
