Abstract
This work investigates the propagation of a monochromatic electromagnetic wave in a periodic layered medium with stepped refractive index. The solution of Maxwell’s equations for piecewise homogeneous medium is proposed by means of which the wave equation in closed form is analytically solved. On the basis of the solution, the propagation of electromagnetic wave in a superlens (Pendry superlens) generated by a metal plate of nanosized thickness has been studied. The computations have proven that, using the superlens, it is possible to achieve angular resolution exceeding the diffraction limit. In addition, it has been demonstrated that negative refraction occurs in such lens.
