Based on the coordinate transformation method, we derived the material parameters for arbitrary N-sided regular polygonal transparent device, which is an important device for antenna protection. The electric field distributions of the device under TE wave and cylindrical wave irradiation are simulated using the finite element solver COMSOL Multiphysics. It shows that although the incident waves are distorted in the transformation region, they return to the original wavefronts when passing through the transformation region. The results of full-wave simulations validate the material parameters for the N-sided regular polygonal transparent device we derived.
