In this study, the design of electric powered VTOL Flying car was made in CAD program, and longitudinal, vertical lateral flight dynamics were examined aerodynamic analysis made. design, power propulsion systems flying car, avionic systems, security magnetic sensors, navigation landing take-off methods, requirement verification performance values determined. Our work for cars, which will soon s...

Light sources with ultra-low energy consumption and high performance are required to realize optical interconnects for on-chip communication. Photonic crystal (PhC) nanocavity lasers one of the most promising candidates fill this role. In work, we demonstrate an electrically-driven PhC nanolaser threshold current 10.2 {\mu}A emitting at 1540 nm operated room temperature. The InP-based bonded on...

Optical antennas play an important role in optical field manipulation. Among them, nanoscale bowtie have been extensively studied for its high confinement and enhancement. In this mini-review, we start with a brief introduction of underlying physics. Then review the applications respect to optically electrically excited antennas. Optically driven enable set such as near-field imaging/trapping, ...
