Abstract
In this article, a 2-D Airy beam with self-bending and non-diffraction characteristics is generated and verified at microwave frequencies by using a metasurface composed of a single-layer of strip resonator. By modifying the rotation angle and structural parameters of the unit cells, the phase and amplitude of the transmission coefficient can be controlled, respectively. In addition, the deflection of the main lobe of the generated 2-D Airy beam can be manipulated by modifying the attenuation coefficients in the 2-D Airy function. The novel excitation and deflection control methods designed in this article propose great application potential in efficient wireless energy transmission at microwave frequencies, particle handling, and integrated beam control systems.
