Abstract :
A novel method for launching an Airy wave packet based on a metallic slit array with stepped-height is proposed. By appropriately adjusting the amplitude and phase of the transmittance from the metallic slit array, the Airy beam can be launched in a compact area. The method can be used in various applications, such as particle tweezing and trapping, without the need for any optical components or bulky structure.
