If you twist something — say, spin a top or rotate a robot’s arm — and want it to return to its exact starting point, ...
Abstract: We propose and simulate a two-dimensional optical phased array using a silicon-based optical integrated circuit. Beam steering is achieved over a range of 11.73° × 11.9° at a fixed ...
Abstract: Compared with traditional low-frequency transmitting antennas, rotating permanent magnet antennas are not limited by electrical size and have the potential to realize the miniaturization of ...
