Abstract

The interaction of ideal and nonideal metamaterial cylindrical cloaks with an electron beam has been studied. The exact solution for energy loss suffered by a fast electron moving inside or outside a cylindrical cloak has been established within a fully relativistic approach. The effect of various imperfect parameters on the efficiency of the cloak has been discussed. It is shown that radiation can be shielded very well by such cloaks when an electron moves either inside or outside of them. The efficiency of nonideal cloaks and the effect of various nonideal parameters on cloak invisibility can be exhibited in the spectra of electron energy loss and radiation emission. This means that the property of a cylindrical cloak can be explored by means of scanning transmission electron microscopy.
