Simultaneous Realization of Coherent Perfect Absorber and Laser by Zero-Index Media with both Gain and Loss
Ping Bai, Kun Ding, Gang Wang +5
We investigate a unique type of zero-index medium with both gain and loss (ZIMGL), whose effective permittivity and permeability are purely imaginary and of opposite signs. We show…

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…
