Coordinate transformation makes perfect invisibility cloak with arbitrary shape
Wei Yan, Min Yan, Zhichao Ruan +1
By investigating wave properties at cloak boundaries, invisibility cloaks with arbitrary shape constructed by general coordinate transformations are confirmed to be perfectly invis…
Cylindrical Invisibility Cloak with Simplified Material Parameters is Inherently Visible
Min Yan, Zhichao Ruan, Min Qiu
It was proposed that perfect invisibility cloaks can be constructed for hiding objects from electromagnetic illumination (Pendry et al., Science 312, p. 1780). The cylindrical cloa…
Confirmation of Cylindrical Perfect Invisibility Cloak Using Fourier-Bessel Analysis
Zhichao Ruan, Min Yan, Curtis W. Neff +1
A cylindrical wave expansion method is developed to obtain the scattering field for an ideal two-dimensional cylindrical invisibility cloak. A near-ideal model of the invisibility…
Enhanced transmission through arrays of subwavelength holes in gold films coated by a finite dielectric layer
Sanshui Xiao, Niels Asger Mortensen, Min Qiu
Enhanced transmissions through a gold film with arrays of subwavelength holes are theoretically studied, employing the rigid full vectorial three dimensional finite difference time…
