Abstract

Based on the theory of coordinate transformation, the design ofelectromagnetic (EM) invisible cloak with a uniform thickness isproposed for arbitrarily polygonal-cylindrical regions. The designedequal-thickness cloak will force incoming EM waves to propagatearound the inner polygonal region smoothly. Similar to the circularcloak, such EM waves will return to their original propagationdirections without distorting the waves outside the cloak. Full-wavesimulations are given to validate the design and analysis.
