Design of mechanically robust metasurface lenses for RGB colors
Jun Yuan, Ge Yin, Wei Jiang +2
In recent years, dielectric rod based metasurface lenses have been particularly investigated for their potential applications in replacing the traditional bulky lens with high effi…
Three-dimensional magnetic cloak working from DC to 250 kHz
Jianfei Zhu, Wei Jiang, Yichao Liu +4
Invisible cloaking is one of major outcomes of the metamaterial research, but the practical potential, in particular for high frequencies (e.g., microwave to visible light), is fat…
High-performance THz metamaterial absorber
Jianfei Zhu, Zhaofeng Ma, Wujiong Sun +4
We demonstrated an ultra-broadband, polarization-insensitive and wide-angle metamaterial absorber for terahertz (THz) frequencies using arrays of truncated pyramid unit structure m…
Experimentally demonstrated an unidirectional electromagnetic cloak designed by topology optimization
Lu Lan, Fei Sun, Yichao Liu +2
Electromagnetic invisible devices usually designed by transformation optics are rather complicated in material parameters and not suitable for general applications. Recently a topo…
Three Dimensional Subwavelength focus by a near-field plate lens
Lu Lan, Wei Jiang, Yungui Ma
We implemented the inverse design method to build a thin near-field lens that could produce a desired subwavelength focus by manipulating the near fields of a magnetic dipole sourc…
First experimental demonstration of an isotropic electromagnetic cloak with strict conformal mapping
Yungui Ma, Yichao Liu, Lu Lan +4
In the past years quasi-conformal mapping has been typically used to design broadband electromagnetic cloaks. However, this technique has some inherit practical limitations such as…
Perfect imaging without negative refraction for microwaves
Yun Gui Ma, C. K. Ong, Sahar Sahebdivan +2
We demonstrate perfect imaging in Maxwell's fish eye for microwaves. Our data show that the field of a line source is imaged with subwavelength resolution over superwavelength dist…
