We fabricated a unique system in which a semiconductor nanowire and a gold bowtie nanoantenna are combined. InP nanowire is precisely placed in the nanogap of the nanoantenna with a nanomanipulator installed in a focused ion beam system. By measuring the intensity mapping of the photoluminescence from the nanowire, we observed a significantly large enhancement at the antenna gap. We also calculated...
As one of the effective way to overcome the digital divide issue in the lightly populated area, the BWA (Broadband Wireless Access) system is expected and field trials have been conducted extensively in Japan. This paper introduces the results of BWA field experiments conducted in a typical intermediate and mountainous area in Japan. In the BWA network, WiMAX units are used as relay stations and R-LAN...
