| description | With the advent and rapid development of the transformation optics and metamaterials, invisibility cloaks have
captivated much attention in recent years. While most cloaking schemes suffer from limited bandwidth, the carpet
cloak, which can hide an object on a reflecting plane, can operate over a broadband frequency range. However, the
carpet cloaks experimentally realized thus far still have several limitations. For example, the quasi-conformal
mapping carpet cloak leads to a lateral shift of the reflected light ray, while the birefringent carpet cloak only
works for a specific polarization. In this work, we propose a conformal transformation scheme to tackle these two
problems simultaneously. As an example, we design a mid-infrared carpet cloak in a silicon platform and demonstrate its polarization-insensitive property as well as the minimized lateral shift over a broad frequency band
from 24 to 28.3 THz. |
