In recent years, there has been a surge of interest in the development of invisibility cloaks that can manipulate electromagnetic waves. This trend stems from the rapid growth of transformation optics and metamaterials technology, which offers exciting opportunities for controlling light propagation across a broad range of frequencies. One particular type of invisibility cloak that has gained significant attention is the carpet cloak. However, previous implementations of carpet cloaks have encountered limitations that hinder their performance in certain contexts. For example, quasi-conformal mapping carpet cloaks are known to produce a lateral shift in the reflected light ray, leading to undesirable effects in imaging applications. Similarly, birefringent carpet cloaks exhibit polarization dependence, which poses major challenges in situations where polarization may vary. To address these drawbacks, we propose a novel approach using an isotropic non-resonant medium and a judiciously designed conformal mapping to develop a carpet cloak. This design approach overcomes previous limitations by enabling the realization of an invisibility cloak for near-IR. Analytical calculations and numerical simulations are conducted to confirm the polarization-robust performance of this near-IR design, which offers superior performance over prior designs. Furthermore, a microwave carpet cloak design are proposed and verified to prove the universality of this approach. By developing this new approach, we hope to contribute to the advancement of cloaking technology and foster its practical applications in various fields.
