A molecuar dynamics simulation has been carried out on the melting behavior of an atomic layer irradiated by thermal radiation. One thousand atoms in this layer are connected to each other by the network of a two-body interatomic potential function. The irradiated electromagnetic radiation is characterized by the wavelength and the phase as well as by the amplitude. The radiation energy is absorbed volumetrically in the atomic layer, and transformed to kinetic energy of the atoms. A solid-liquid interface is found to appear at the surface of the layer, and to propagate into the inner part of the layer. Clear difference in atomic configuration and atomic movement has been observed between the solid and liquid phases. Successive irradiation causes the evaporation of atoms in the liquid phase, and atoms in the liquid and gas phases reach their critical state in the closed system of this simulation model.
