A new strategy to conceal an object from electromagnetic wave
Yu Luo, Jingjing Zhang, Hongsheng Chen +2
A new recipe for concealing objects from detection is suggested. Different with traditional cloak which deflects light around the core of the cloak to make the object inside invisi…
Freely-suspended matrix-free metamaterials showing THz left-handed pass bands
H. O. Moser, J. A. Kong, L. K. Jian +12
Featuring dense spatial distributions of engineered metallic particles, electromagnetic metamaterials exhibit simultaneously negative values of both, dielectric permittivity and ma…
Directive Emission Obtained by Coordinate Transformation
Jingjing Zhang, Yu Luo, Hongsheng Chen +3
We use coordinate transformation theory to realize substrates that can modify the emission of an embedded source. Simulation results show that with proper transformation functions…
Design and analytically full-wave validation of the invisibility cloaks, concentrators, and field rotators created with a general class of transformations
Yu Luo, Hongsheng Chen, Jingjing Zhang +2
We investigate a general class of electromagnetic devices created with any continuous transformation functions by rigorously calculating the analytical expressions of the electroma…
Extraordinary surface voltage effect in the invisibility cloak with an active device inside
Baile Zhang, Hongsheng Chen, Bae-Ian Wu +1
The electromagnetic field solution for a spherical invisibility cloak with an active device inside is established. Extraordinary electric and magnetic surface voltages are induced…
