WebSep 4, 2024 · The invisible effect is revealed by near-field and far-field distribution for the ground plane, bare bump, and cloak, respectively. Our designed cloaking with the metasurface composed of five-layer unit cell structure has a good invisible effect at the broadband range from 0.7 to 0.8 THz and has a wide-angle response from 35 to 50°. 1 …

WebJun 4, 2012 · We demonstrate a finite-difference time-domain (FDTD) modeling of a cloak with a nondiagonal permittivity tensor. Numerical instability due to material anisotropies is avoided by mapping the eigenvalues of the material parameters to a dispersion model. Our approach is implemented for an elliptic-cylindrical cloak in two dimensions.
