Abstract :
A directional cloaking device based on the transformation electromagnetics approach for a ground-plane cloak in the visible spectrum is presented. A simplified cloak consisting of 16 all-dielectric blocks is illuminated under plane wave incidence. The field distributions, the scattered energy and the frequency spectrum of the incident pulse are also analyzed. It is found that the simplified cloak works very similar to the full high-resolution cloak. Finite-difference time-domain simulations are used to quantify the electromagnetic performance of the device.
