Atomic mirror

Atomic mirrors can be made of electric fields or magnetic fields,[1] electromagnetic waves[2] or just silicon wafer; in the last case, atoms are reflected by the attracting tails of the van der Waals attraction (see quantum reflection).[3][4][5] Such reflection is efficient when the normal component of the wavenumber of the atoms is small or comparable to the effective depth of the attraction potential (roughly, the distance at which the potential becomes comparable to the kinetic energy of the atom).To reduce the normal component, most atomic mirrors are blazed at the grazing incidence.[6][7][8][9] The set of narrow ridges reduces the van der Waals attraction of atoms to the surfaces and enhances the reflection.Frequent measuring (narrowly spaced ridges) suppresses the transition of the particle to the half-space with absorbers, causing specular reflection.
