During several last years it was shown that an electromagnetic field can be made to curve after propagation
through a simple dielectric material of special shape. This effect was termed ‘photonic hooks’ — it is a unique electromagnetic beam configuration behind a mesoscale dielectric Janus particle and differ from Airy-family beams. THz photonic hooks 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. Below we report an experimental verification of the photonic hook phenomenon in THz band.
