In this article we consider loss for all parts of external cloaks that are achieved by the different transformation functions. Each cloak has a different threshold for loss. We compare the simulation result with each other to find the best function for external cloaking.

An electromagnetic cloak is a device which makes an object "invisible" for electromagnetic irradiation in a certain frequency range. Material parameters for the complementary medium-assisted external cylindrical cloak with N-sided regular polygonal cross-section are derived based on combining the concepts of complementary media and transformation optics. It can make the object with an arbitrary shape outside the cloaking domain invisible, as long as an "anti-object" is embedded in the complementary layer. The external cloaking effect has been verified by full-wave simulation.
