Local CO2 laser treatment has proved to be an effective method to prevent the 351-nm laser-induced damage sites in a fused silica surface from exponentially growing, which is responsible for limiting the lifetime of o...
Beyond the third generation mobile communications, high-capacity and high-speed wireless transmission causes serious Co-Channel Interference (CCI) and Inter-Symbol Interference (ISI). This paper first set up a kind of...
