Recent technical developments in laser and nanotechnology show great promise as it allows us to overcome the aforementioned problems. Advanced laser technique has triggerd various studies of manipulating particles by externally applied field. At an earlier stage, it has led to the success of laser cooling and trapping which give rise to the creation of ultracold atoms [MOT, Sisyphus, molasses, zeeman]. Ultracold atoms can act as a powerful tool to manipulate atomic waves coherently [quantum ref Shimizu, MIT, interf] by allowing us to prepare sources of coherent atomic waves. Furthermore, laser-tuning enables us to observe Bragg scattering and Kapitza-Dirac effect of atomic waves by adjusting detuning frequency[ref] and it motivated the first approach(or implementation of) to the practical atomic mirror which refers to as evanescent wave mirror [ref]. 
 On the other hand, nanotechnology have provided a major breakthrough in developing nano-fabricated devices, which can serve as atom-optical elements such as transmission grating[ref] and Fresnel zone plate[ref]. 
Thus, Recent technical developments in laser and nanotechnology show great promise as it allows us to overcome the aforementioned problems.  
It has been reported that at specific detuning frequency, the reflectivity of atoms scattered off the evanescent wave mirror goes up to almost 1 [ret].
 However, size-limit//
 In the meanwhile, various methods to manipulate particles [\citep{Ashkin_1970}\citep{Chu_1986}\citep{Stapelfeldt_1997}], which have been actively studied over past few decades, led to the success of laser colling and trapping. Those techniques have given rise to the creation of ultracold atoms [MOT, Sisyphus, molasses, zeeman] which act as a powerful tool to manipulate atomic waves coherently [quantum ref Shimizu, MIT, interf] by allowing us to prepare sources of coherent atomic waves. Thus,
 In a short while, a totally new mechanism of matter-wave reflection has been demonstrated by observing quantum refleciton of metastable neon atoms from the solid surface. Quantum reflection is 
the development of atom optics has been opened up based on those studies of controlling the motion of the atoms.
