Directional control of light by a nano-optical Yagi-Uda antenna
FREE-DOWNLOADT Kosako, Y Kadoya… – Nat. Photonics, 2010 – The plasmon resonance of metal nanoparticles can direct light from optical emitters in much the same way that radio- frequency antennas direct the emission from electrical circuits. Recently, rapid progress has been made in the realization of single-element antennas for

FREE-DOWNLOADL Cao, P Fan, AP Vasudev, JS White, Z Yu… – Nano letters, 2010 Photovoltaic (PV) cells can serve as a virtually unlimited clean source of energy by converting sunlight into electrical power. Their importance is reflected in the tireless efforts that have been devoted to improving the electrical and structural properties of PV materials. […]
Power allocation for a MIMO relay system with multiple-antenna users
FREE-DOWNLOAD Y Yu… – Signal Processing, research Transactions on, 2010 – Abstract—A power allocation or scheduling problem is studied for a multiuser multiple-input multiple-output (MIMO) wireless relay system where there is a non-regenerative relay between one access point and multiple users. Each node in the system is equipped with multiple
