Breakdown of Maxwell Garnett theory due to evanescent fields at deep-subwavelength scale
Ting Dong, Jie Luo, Hongchen Chu +2
Deep-subwavelength all-dielectric composite materials are believed to tightly obey the Maxwell Garnett effective medium theory. Here, we demonstrate that the Maxwell Garnett theory…
Broadband perfect absorption of ultrathin conductive films with coherent illumination:Superabsorption of microwave radiation
Sucheng Li, Jie Luo, Shahzad Anwar +7
Absorption of microwave by metallic conductors is exclusively inefficient, though being natively broadband, due to the huge impedance mismatch between metal and free space. Reducin…
A unified theory for perfect absorption in ultra-thin absorptive films with constant tangential electric or magnetic fields
Jie Luo, Sucheng Li, Bo Hou +1
The maximal absorption rate of ultra-thin films is 50% under the condition that the tangential electric (or magnetic) field is almost constant across the film in symmetrical enviro…
Realizing bending waveguides with anisotropic epsilon-near-zero metamaterials
Jie Luo, Ping Xu, Huanyang Chen +2
We study metamaterials with an anisotropic effective permittivity tensor in which one component is near zero. We find that such an anisotropic metamaterial can be used to control w…
