Electrical manipulation of plasmon-phonon polaritons in heterostructures of graphene on biaxial crystals
Zhiyong Li, Zefeng Chen, Jingwen Ma +4
Phonon polaritons in natural anisotropic crystals hold great promise for infrared nano-optics. However, the direct electrical control of these polaritons is difficult, preventing t…
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…
Experimental demonstration of a multiphysics cloak: manipulating heat flux and electric current simultaneously
Yungui Ma, Yichao Liu, Muhammad Raza +2
In past years, triggered by their successful realizations in electromagnetics, invisible cloaks have experienced rapid development and have been widely pursued in many different fi…
An efficient plate heater with uniform surface temperature engineered with effective thermal materials
Yichao Liu, Wei Jiang, Sailing He +1
Extended from its electromagnetic counterpart, transformation thermodynamics applied to thermal conduction equations can map a virtual geometry into a physical thermal medium, real…
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…
A transient thermal cloak experimentally realized through a rescaled diffusion equation with anisotropic thermal diffusivity
Yungui Ma, Lu Lan, Wei Jiang +2
Transformation optics originating from the invariance of Maxwell's equations under the coordinate mapping has enabled the design and demonstration of many fascinating electromagnet…
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…
