Translation and Rotation of Transformation Media under Electromagnetic Pulse
Fei Gao, Xihang Shi, Xiao Lin +2
It is well known that optical media create artificial geometry for light, and curved geometry acts as an effective optical medium. This correspondence originates from the form inva…
Invisibility Dips of Near-Field Energy Transport in a Spoof Plasmonic Metadimer
Fei Gao, Zhen Gao, Yu Luo +1
Invisibility dips, minima in scattering spectrum associated with asymmetric Fano-like line-shapes, have been predicted with transformation optics in studying strong coupling betwee…
Spoof surface plasmon Fabry-Perot open resonators in a surface-wave photonic crystal
Zhen Gao, Fei Gao, Hongyi Xu +2
We report on the proposal and experimental realization of a spoof surface plasmon Fabry-Perot (FP) open resonator in a surface-wave photonic crystal. This surface-wave FP open reso…
Tunable band-notched line-defect waveguide in a surface-wave photonic crystal
Zhen Gao, Fei Gao, Youming Zhang +2
We propose and experimentally demonstrate a tunable band-notched line-defect waveguide in a surface-wave photonic crystal, which consists of a straight line-defect waveguide and si…
Sign-Reversal Coupling in Coupled-Resonator Optical Waveguide
Zhen Gao, Fei Gao, Youming Zhang +1
Coupled-resonator optical waveguides (CROWs), which play a significant role in modern photonics, achieve waveguiding through near-field coupling between tightly localized resonator…
Guiding, bending, and splitting of coupled defect surface modes in a surface-wave photonic crystal
Zhen Gao, Fei Gao, Baile Zhang
We experimentally demonstrate a type of waveguiding mechanism for coupled surface-wave defect modes in a surface-wave photonic crystal. Unlike conventional spoof surface plasmon wa…
