Photonic band gap of a graphene-embedded quarter-wave stack
Yuancheng Fan, Zeyong Wei, Hongqiang Li +2
Here, we present a mechanism for tailoring the photonic band structure of a quarter-wave stack without changing its physical periods by embedding conductive sheets. Graphene is uti…
Enhancing infrared extinction and absorption in a monolayer graphene sheet by harvesting the electric dipolar mode of split ring resonators
Yuancheng Fan, Zeyong Wei, Zhengren Zhang +1
Optical extinction and absorption enhancement in the infrared range of a monolayer graphene sheet by patterning split ring resonators (SRRs) is studied. It is found that the electr…
Gaussian Beam Collimation via Transformation Media
Yuancheng Fan, Jin Han, Hongqiang Li
Conventional method for Gaussian beam collimation is to expand the beam waist to achieve a smaller divergence angle. Recent transformation optics offers an unconventional path to c…
