The　Airy　beam,　known　to　present　particular　unique　features,　such　as　diffraction-free,　self-healing,　and　self-bending,　has　attracted　considerable　interest　in　recent　years.　Here,　an　electronically　controlled　reflective　coding　metasurface　is　exploited　to　generate　and　dynamically　manipulate　the　Airy　beam　over　a　wide　frequency　band　in　the　microwave　regime.　By　judiciously　controlling　the　external　dc　bias　voltage　applied　to　the　programmable　metasurface,　two　distinct　control　states,　＇0＇and　＇1＇,　are　engineered　as　digital　codes　for　-π/2　and　+π/2　phase　responses,　respectively.　The　programmable　binary-phase-coding　metasurface　enables　the　generation　and　active　reshaping　of　the　Airy　beam　to　be　numerically　simulated　and　experimentally　validated.　Moreover,　the　metasurface　allows　the　bandwidth　limitation　of　passive　counterparts　to　be　overcome　and　is　able　to　modulate　electromagnetic　waves　over　a　broad　frequency　range,　spanning　from　9　to　12　GHz,　to　realize　diffraction-free　Airy　beams.　©　2020　American　Physical　Society.
