Abstract
We examine selective reflection (SR) spectrum of an Airy beam at an interface between a dielectric and a homogeneous atomic medium. It is shown that both the general reflection (GR) and the SR of Airy beams exhibit accelerating dynamics with a parabolic trajectory, however, the accelerating rate for the SR is slightly greater than that for the GR. Due to interaction of atoms and the Airy beams at the interface between dielectric and resonant atoms, the SR beams can create far-field interference patterns. We also show that the amplitude of the SR can be dramatically modified by the detuning of the incident fields, the reduced x-coordinate and the distance from the interface. The SR at the resonant medium interface of Airy beams can probably be a powerful tool in the use of optical power delivering, resonant particle manipulation and spatial spectrum detection of a resonant medium at an interface.

The parabolic trajectories of the selective reflection (SR) beams are similar to the case of the general reflection (GR) beams, the accelerating rate in the former case is slightly greater than that in the latter case
Summary
An Airy wavepacket was initially predicted within the context of quantum mechanics [1]. It has two typical properties: resistance to diffraction and accelerating dynamics along the transverse direction during the propagation [2,3] These remarkable features of ideal Airy beams can be implemented in practice by finite power Airy beams maintaining their shape over several diffraction lengths before they are significantly distorted [2,3]. It was shown that an Airy beam can maintain its shape when propagating in a self-defocusing nonlinear medium [6] These exotic features of Airy beams may have many applications, e.g., controlling of beam trajectory [7], particle manipulation [8], plasma channel generation [9] and near-field imaging of Airy surface plasmons [10]. The selective reflected Airy beam can probably be a powerful tool in the use of optical power delivering, resonant particle manipulation and spatial spectrum detection of a resonant medium at an interface
