Abstract

V originále

We investigate the scattering properties of the invisible lens in two ways. First, we describe the scattering of electromagnetic waves by the invisible lens realised by a purely dielectric, purely magnetic, and impedance-matched medium, respectively, using Debye potentials. Second, we employ the Wentzel–Kramers–Brillouin method to analyse the scattering of scalar waves by the lens. We show that in all cases the scattering is negligible for a discrete set of frequencies, while for other frequencies there is a phase slip at the boundary of the lens 'shadow'.

In Czech

V článku analyzujeme rozptyl elektromagentických vln na tzv. neviditelné čočce dvěma způsoby. Jednak pro plně vektorový popis pomocí Debyeových potenciálů, jednak pomocí WKB metody pro skalární vlny. V obou případech se ukazuje, že rozptyl je zanedbatelný pro diskrétní sadu rezonančních frekvencí.
