We have shown that, by properly detuning the carrier frequencies in each of two perpendicularly intersecting bichromatic waves from the atomic transition frequency, it is possible to create a two-dimensional trap for atoms, if the wave intensities are sufficiently high. At the zero and near-zero values of the initial wave phases, as well as at the phase shift between the intersecting waves equal to п or close to п values, the dynamic spatial patterns of atoms consisting of square cells with the side length equal to л/√2 are formed. Numerical simulations were carried out for sodium atoms.
