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, ...

Unmanned robots being remotely controlled or autonomous are spread worldwide and used in different purposes. Inhabited brought very close to users accessibility these tools is high, moreover, at low costs. Regardless emphasize the increasing popularity of robots. However, any robot system electrically driven has bottleneck amount electrical energy stored aboard battery packs. In other words, du...

In this paper, a combined adaptive-robust and neural network control based on backstepping design is proposed for trajectory tracking of two 6-DOF rigid link electrically driven (RLED) elbow robot manipulators moving a rigid object when actuator dynamics is also considered in the system dynamics. First, the authors derive kinematics and dynamics of the mechanical subsystem and the relations amo...
