Abstract

In this paper we present a new model to describe the interaction of electromagnetic waves with spheres covered by metamaterials. The model is based on a field expansion and the definition of reflection coefficients as ratios between travelling waves. The introduced formulation allows a clear physical interpretation of several electromagnetic scattering phenomena. In this work, it is used to investigate the scattering suppression that is the phenomenon that allows the cloaking of spherical objects. The obtained results are consistent with other published results and introduce a new interpretation framework that can be used to design future materials in a plethora of applications.
