Cloaking of 2D particle geometries in a surface medium

► General solutions for the cloaking of arbitrary 2D geometries are derived. ► Cloaking is obtained via all positive or partially negative constitutive parameters. ► Cloaking of multi-layered particle geometries is given. ► It is shown that cloaking of particle geometries is independent of frequency. ► Cloaking of particle geometries that are large compared to the wavelength is obtained.
