查询词典 waveguide

Based on the results of the theory analysis and computer simulation of ratrace, Waveguide-to-Microstrip Probe Transitions, DGS lowpass filter, the structure was designed and manufacture was made.

在对所用到的功率混合电路，波导－微带探针过渡，以及DGS低通滤波器进行理论分析、计算、和计算机仿真的基础上，制作混频器，并对设计结果进行了测试验证。

We find that the localized waveguide transmission peak redshifts and becomes broader along with the layer distance D increasing.

本工作发现随着板间距D 的增大，局域波导共振峰发生红移，同时峰的宽度明显变宽。

Cherenkov radiation in a plasma-filled dielectric coaxial waveguide.

填充等离子体的介质同轴波导中的切伦科夫辐射。

It was clear that the Cherenkov radiation is result of the coupling between the slow TM mode propagated along the waveguide and the negative-energy space-charge mode propagated along the beam, and the coupling strength is proportional to the beam density.

分析结果表明：切伦科夫辐射是由沿介质同轴波导传播的慢波与沿薄环形相对论电子注传播的负能空间电荷波耦合所致，且其耦合强度与电子注的密度成正比；输出频率和波增长率随着填充等离子体密度的增大而提高；保持一定的输出频率，增大电子注的束流可得到高的微波输出功率。

A method for preparing planar light waveguide by using ultra-short laser pulses includes such steps as using low-aperture N.A.

本发明公开了一种利用超短激光脉冲制备平面光波导的方法。根据制备平面光波导所需的宽度，选用N.A。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.

为了得到适合有限元分析的模型，我们必须经过如图2所示的简化步骤。
