Based on the theory of coordinate transformation, the design of electromagnetic (EM) invisible cloak with a uniform thickness is proposed for arbitrarily polygonal-cylindrical regions. The designed equal-thickness cloak will force incoming EM waves to propagate around the inner polygonal region smoothly. Similar to the circular cloak, such EM waves will return to their original propagation directions without distorting the waves outside the cloak. Full-wave simulations are given to validate the design and analysis.
