Beyond near-infrared lossy mode resonances with fluoride glass optical fiber
The objective of this Letter consists of the exploration of the lossy mode resonance (LMR) phenomenon beyond the nearinfrared region and specifically in the short wave infrared region (SWIR) and medium wave infrared region ... -
Bloch waves at the surface of a single-layer coating D-shaped photonic crystal fiber
Bloch surface wave (BSW) platforms are particularly interesting for light confinement and surface sensitivity, as an alternative to the metal-based surface plasmon polaritons (SPP). However, most of the reported BSW platforms ... -
Broadband 3-D shared aperture high isolation nine-element antenna array for on-demand millimeter-wave 5G applications
The paper presents the results of a novel 3-D shared aperture 3 × 3 matrix antenna-array for 26 GHz band 5 G wireless networks. Radiation elements constituting the array are hexagonal-shaped patches that are elevated ... -
Building decentralized fog computing-based smart parking systems: from deterministic propagation modeling to practical deployment
The traditional process of finding a vacant parking slot is often inefficient: it increases driving time, traffic congestion, fuel consumption and exhaust emissions. To address such problems, smart parking systems have ... -
