In this paper, we carry out the numerical simulation of spherical superlens by the Dyadic Green’s function method, and we prove the sub-wave length imaging capability of spherical superlens. Dyadic Green’s function method is an effective method and a systematic theory of dealing with the problem of electromagnetic fields, which makes up the deficiencies in coordinate transformation method. Compared with the flat lens, the spherical superlens have several advantages, including the finiteness cross-section, and ability in lensing with magnification or demagnification, high resolution, two-dimensional imaging, etc.
