| Popis: | we demonstrate an analytical approach to find monotone and wideband cloaking by using equivalent conductivity method. This method gives us a straightforward tool to design the metasurface with an appropriate reactance. The equivalent conductivity is achieved with the aid of the polarizability of a nanoparticle that constituting the metasurface. The designed metasurface covered the dielectric cylinder plays cloaking shell role and dramatically decreases the scattering from the cloaked object. This scattering reduction is evaluated numerically and compared with uncloak situation from far infrared to near infrared wavelength ranges. |
