基于计算得到的直弯波导的模场分布，采用二维重叠积分法计算了两者连接时的过渡损耗。 - Second , the mode fields of a strip waveguide and some slab waveguides have been simulated by applying finite - difference time - domain ( fdtd ) method . the curvature radius ; vicinity coupling ; transition loss and power attenuation of a s - shape bend waveguide have been analysed numerically by employing wide angle finite - difference beam propagation method ( fd - bpm ) , as well as the coupling loss of optical fiber and waveguide . in addition , the framework of the s - shape waveguide laser has been
其次,应用时域有限差分法,结合波导模式理论对条形与平面波导进行了模场仿真;应用广角有限差分光束传播法,对s形弯曲波导的曲率半径、邻近耦合、过渡损耗、功率衰减以及波导与光纤的各种耦合损耗进行了数值分析,并在此基础上,对s形波导激光器的结构作了初步设计。 - In this dissertation , the varied characteristics of soi rib waveguide were investigated , and the calculated results as well as simulated plots in theory were presented . it was the first time that a 3d overlap integral method was used to calculate the transition loss between the rib waveguides and the slab waveguides , in which the effect of the mode distribution in rib waveguides on the coupling efficiency was taken into account
针对上述问题，本论文对soi波导的各种特性进行探讨并给出了详细的计算结果，首次用三维功率交迭积分法计算了soi波导器件中波导过渡区的损耗，这种方法考虑了脊形波导模式分布对过渡区耦合效率的影响。 - There are distinct changes about shifts or intensity in bulk plasmon , surface plasmon , and interband electron transitions losses as a result of oxidation of specimens , and adsorption and oxidation processes can be studied through these changes . at room temperature , the formation of oxide layers on uranium and uranium - niobium alloys were found to occur rapidly upon exposure to oxygen , and the resultant oxide in each case was near - stoichiometric uo2 . due to formation of niobium oxide in uranium - niobium alloys , the diffusion of o ~ ( - ) ( o ~ ( 2 - ) ) and u ~ ( 4 + ) in the interface region was prevented , and the corrosion resistance of uranium - niobium alloys to oxygen is greatly enhanced by alloying with niobium
研究结果表明：清洁表面铌和铀的体等离子体振荡所造成的电子能量损失的实验值与理论计算值较为符合；随着氧化程度的加剧，表面等离子体( sp ) 、体等离子体( bp )以及价带电子跃迁所造成电子能量损失的谱峰发生了明显的连续偏移或强度的变化，这些变化可以用来分析铀及铀铌合金的初始氧化过程；室温下，铀及铀铌合金很容易与氧作用，最终结果，铀仅氧化为二氧化铀，另外，在铀铌合金氧化过程中，因为有铌的氧化物存在，不利于氧和铀在界面扩散，增强了铀铌合金抗氧化性能； eels能获得样品表面的信息比aes更为表面，更为灵敏，但由于eels的谱线过于集中，主要在几十ev以内，也有不容易区别和解谱的不足。
