- Example Sentences:
| 1. | For the negative uniaxial crystal material , the principal mode is a hybrid guided mode , which can also be excited by the light at any frequency , but when the single mode propagation condition can not be satisfied , some of the higher order hybrid guided modes will exist in the waveguide 对于负单轴晶体,波导的主模是混合模hgm _ 0模,该模式同样可被任何频率的光波所激励;当光波波长满足一定条件时,波导内传输单模,否则,将激励起高阶混合模。 | | 2. | The most achievement is that we firstly obtain the analytic accurate solution of the modal fields of the waveguide structure and find some available character : ( 1 ) the different uniaxial crystal materials have the different propagation properties ; ( 2 ) when the optical axis of the crystal is on the plane that is made up of the normal direction of the waveguide plane and the propagation , there are te mode and tm mode in this special waveguide , but the principal mode is different of the character of the uniaxial crystal , the principal mode is the principal mode of te mode for the negative uniaxial crystal , but the one of tm mode for the positive uniaxial crystal ; ( 3 ) when the crystal optical - axis parallel to the waveguide plane , for the positive uniaxial crystal material , the principal mode of the waveguide is a te wave , which can be excited by the light at any frequency ; when the light frequency satisfies a single mode propagation condition , there will be only the principal mode propagating in the waveguide , otherwise some of the higher order modes can be excited , which are neither te modes , nor tm modes , but the hybrid guided modes 本文就是在此背景下,利用金属波导和单轴晶体的一些特性,结合麦克斯韦方程组和波导的边界条件,从三种不同的情况研究了光在对称平面单轴晶体金属波导(波导层是单轴晶体,两个波导界面均为金属)内的传输特性,其主要贡献为,首次解析地得到了这种波导结构下模式场的精确解,并发现了一些有用的特性: ( 1 )模式场的性质因单轴晶体的性质不同而异; ( 2 )当单轴晶体光轴位于波导界面法方向与传输方向构成的平面内时,波导中传输te波和tm波,只不过其主模因单轴晶体的性质不同而异,当波导层介质为负单轴晶体时,波导主模是te波主模,而波导层介质为正单轴晶体时波导主模是tm波主模。 ( 3 )当单轴晶体光轴位于波导面内时,对于正单轴晶体,波导的主模是横电波te _ 0模,任何频率的光波均可激励该模式;当光波波长满足一定条件时,波导内传输单模,否则,将激励起高阶模式,高阶模即匪te波,也匪tm波,而是两者耦合而成的混合模。 | | 3. | Simulation results show that : i ) the m - lwdf algorithm is a viable solution for scheduling streaming flows in hsdpa ; ii ) this algorithm is unfair because it provides a better qos to users under favourable propagation conditions ; and iii ) a maximum node b queuing of 2 ~ 3 seconds represents a good compromise between cell throughput and delay jitter introduced in the node b for streanming 仿真结果表明, m - lwdf算法适合于hsdpa中流用户的调度服务,但它是一种不公平的算法,总是选择为信道条件好的用户提供更好的qos 。当应用于固定比特速率流业务时,对m - lwdf算法作了一些修改,使得修正后的算法在用户公平性上有了改进,但是不可避免地引起了系统吞吐量的下降。 |
