title: Frequency scanning from subwavelength aperture array.
abstract: Resonant transmission of microwaves is demonstrated through subwavelength holes on a semicircular radiator. Split ring resonators, offering a perfect control of the emitting apertures, are applied to determine the radiation direction and the resonant frequency. Full wave simulation shows that our design is capable of achieving wide angular scanning beams without causing any other main lobe, and the steerable beams could be easily controlled through tuning the excitation frequency.
