Field-Effect Transistors Based on Few-Layered alpha-MoTe_2
Nihar R. Pradhan, Daniel Rhodes, Simin Feng +6
Here we report the properties of field-effect transistors based on few layers of chemical vapor transport grown alpha- MoTe_2 crystals mechanically exfoliated onto SiO_2. We perfor…
Directional perfect absorption using deep subwavelength low permittivity films
Ting S. Luk, Salvatore Campione, Iltai Kim +8
We experimentally demonstrate single beam directional perfect absorption (to within experimental accuracy) of p-polarized light in the near-infrared using unpatterned, deep subwave…
Loss enhanced transmission and collimation in anisotropic epsilon-near-zero metamaterials
Lei Sun, Simin Feng, Xiaodong Yang
We verify the extraordinary transmission enhancement and collimation induced by the material loss in anisotropic near-zero permittivity (ENZ) metamaterials, and reveal the physical…
Omnidirectionally Bending to the Normal in epsilon-near-Zero Metamaterials
Simin Feng
Contrary to conventional wisdom that light bends away from the normal at the interface when it passes from high to low refractive index media, here we demonstrate an exotic phenome…
Perfect Absorption in Ultrathin Epsilon-Near-Zero Metamaterials Induced by Fast-Wave Non-Radiative Modes
Simin Feng, Klaus Halterman
Above-light-line surface plasmon polaritons can arise at the interface between a metal and epsilon-near-zero metamaterial. This unique feature induces unusual fast-wave non-radiati…
Exotic leaky wave radiation from anisotropic epsilon near zero metamaterials
Klaus Halterman, Simin Feng, Viet Cuong Nguyen
We investigate the emission of electromagnetic waves from biaxial subwavelength metamaterials. For tunable anisotropic structures that exhibit a vanishing dielectric response along…
