General expressions of constitutive tensors of the N-sided regular polygonal cylindrical cloaks are derived based on the coordinate transformation theory, then there are some full-wave simulations of the cloaks.The results of full-wave simulations validate the general expressions of constitutive tensors we derived. Furthermore, factors that degrade the cloaks invisibility are analyzed.
