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 longas an anti-object is embedded in the complementary layer. The external cloaking effect has been verified by full-wave simulation.
