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…
An ultra-thin waveguide twist constructed using fish-scale metallic wires
Jin Han, Hongqiang Li, Yuancheng Fan +6
This study theoretically and experimentally investigates the transmission properties of a metamaterial slab comprised of two layers of metallic fish-scale structure arrays and a sa…
Subwavelength electromagnetic diode: one-way response of cascading nonlinear meta-atoms
Yuancheng Fan, Jin Han, Zeyong Wei +4
We propose a scheme for realizing subwavelength electromagnetic diode by employing cascading nonlinear meta-atoms. One-way response is demonstrated on a microwave transmission line…
Broadband negative refraction in stacked fishnet metamaterial
Zeyong Wei, Yang Cao, Jin Han +3
We demonstrate a scheme to utilize the stacked fishnet metamaterial for all-angle negative refraction and subwavelength imaging within a wide frequency range starting from zero fre…
Acoustic cloaking and imaging using complementary media
Jin Han, Yuancheng Fan, Hongqiang Li +1
Base on the concept of complementary media, a scheme to achieve cloak an object outside the shell is proposed by Yun lai et al [PRL 102, 093901].We generalize the concept in acoust…
