Deep-subwavelength magnetic-coupling-dominant stereometamaterials
Zhen Gao, Fei Gao, Youming Zhang +1
Here, we experimentally demonstrate that a stack of metallic spiral structures (MSSs) can have dominant magnetic coupling in both of its two configurations. This allows magnetic-co…
Complementary magnetic localized surface plasmons
Zhen Gao, Fei Gao, Youming Zhang +1
Magnetic localized surface plasmons (LSPs) supported on metallic structures corrugated by very long and curved grooves have been recently proposed and demonstrated on an extremely…
Vertical Transport of Subwavelength Localized Surface Electromagnetic Modes
Fei Gao, Zhen Gao, Youming Zhang +3
Transport of subwavelength electromagnetic (EM) energy has been achieved through near-field coupling of highly confined surface EM modes supported by plasmonic nanoparticles, in a…
Dynamical Mechanism of Two-Dimensional Plasmon Launching by Swift Electrons
Xiao Lin, Xihang Shi, Fei Gao +8
Launching of surface plasmons by swift electrons has long been utilized in electron-energy-loss spectroscopy (EELS) to investigate plasmonic properties of ultrathin, or two-dimensi…
Probing topological protection using a designer surface plasmon structure
Fei Gao, Zhen Gao, Xihang Shi +9
Topological photonic states, inspired by robust chiral edge states in topological insulators, have recently been demonstrated in a few photonic systems, including an array of coupl…
