In understanding of the hot spot phenomenon in single-molecule surface enhanced Raman scattering (SM-SERS), electromagnetic field within gaps dimers (i.e., two particle systems) has attracted much interest as it provides significant amplification over single isolated nanoparticles. addition to existing dimer systems, we show this paper that enhancement a chain could maximize at number N>2, due near-field coupled plasmon resonance chain. This effect was theoretically observed for gold (Au)...
The authors present a simple and efficient technique for laser writing of arbitrary nanopatterns across large surface area without using projection masks. It is based on the unique near-field focusing effect self-assembled particle array interacting with an angular incident beam. spot resolution can be down to 80nm. More than 6×106 nanolines c-shaped uniform patterns were fabricated simultaneously over 5×5mm2 by few shots.
The large differences in physical and thermal properties of the carbon fibre-reinforced polymer (CFRP) composite constituents make laser machining this material challenging. An extended heat-affected zone (HAZ) often occurs. availability ultrashort pulse sources such as picosecond lasers makes it possible to improve quality these materials. This paper reports an investigation on drilling CFRP composites using a state-of-the-art 400 W system. Small HAZs (<25 µm) were obtained entry side...
Mushroom-like electromagnetic band gap (EBG) structures exhibit unique properties that have found a wide range of device applications. This paper focuses on the local resonance behaviors EBG structures, and simply locally resonant cavity cell (LRCC) model for mushroom-like is presented to gain insight physical mechanism interaction waves with structures. The LRCC proposes two kinds main modes: One mono-polarized mode accurately predicts position surface wave suppression bandgap, which...
