On the basic of the coordinate transformation theory, we deduce the condition for irregular polyhedron cloaks and obtain tensor expressions of electromagnetic parameters. Using tensor expressions of electromagnetic parameters, we verify the effect of 4-sided polyhedron cloak and 14-sided polyhedron cloak through full-wave simulations. The results confirm the validity of tensor expressions of electromagnetic parameters we derived. The present work may serve as a basis for the design of three-dimensional baroque cloak.
