Abstract
We propose an innovative cloak to enable different sizes, shapes and also constituent parameters of arbitrary hidden objects not only to observe the fields with 360-degree eyesight from the environment outside the cloak but also to need neither to be 'custom-made' nor to be confined by the position of the corresponding anti-objects. We design the spatially varying constituent parameters of an innovative cloak by the aid of transformation optics with two steps of coordinate transformations and testify the performances of an innovative cloak by COMSOL simulation software. Herein, we demonstrate the corresponding E z field distribution as a testimony of invisible hidden objects and claim that the simulation results demonstrate a good agreement with analytical study of an innovative cloak. © 2012 SPIE.
