A rigorous theory of propagation of an electromagnetic wave from a point elementary current source is considered when it is focused by a plane layer filled with a material with a negative refractive index (Veselago lens). The distributions of the electromagnetic field in the focal region are investigated and its dimensions are determined. Key theoretical questions are discussed in detail.
