Abstract
Previous methods for the generation of accelerating beams are mostly based on bulky phase-only spatial light modulator. Here we propose an experimental scheme for the generation of accelerating beams by fabricating a quartz plate capable of realizing both phase and amplitude modulation. The phase modulation is implemented by aligned 16-level etching into the quartz plate, while the amplitude modulation is realized by controlling the duty ratio of the partial metal coverage locally. Based on this approach, a sinusoidal accelerating beam with multiple bending is generated for demonstration and propagates along a sinusoidal trajectory as expected.
