Abstract
We study the possibilities of using the eikonal equation to construct theoretical models of objects that become invisible under certain illumination conditions. The characteristics of the cloaking coating, which performs its functions for a given direction of wave incidence on the cloaked volume of space, are calculated. A method for constructing models of cylindrical objects that are invisible at arbitrary azimuthal and given zenith angles of illumination is proposed. It is shown that by employing the eikonal equation, it is possible to design invisible objects from materials with refractive indices of different signs.
