静磁波 meaning in English
magnetic static wave
msw magnetostatic wave
Examples
- Magnetostatic wave ( msw ) is a kind of slow dispersive wave propagating in magnetic medium , which is also a microwave electromagnetic wave . so the propagation characteristics of msw can be controlled by bias magnetic fields
静磁波( msw )是一种在磁性介质中传播的慢色散波,也是一种微波电磁波,可通过磁控方法改变静磁波的传播特性,并与具有电磁性的物质发生作用。 - The microwave delaylines using hts thin films have the advantages of small size and mass and low insertion lose . these characters are much better than the delaylines using surface acoustic wave , coaxial - line , magetostatic wave or conventional metal planar structures . these merits benefit a lot in largely reduction the mass and volume of communication systems
利用高温超导( htsc )薄膜材料研制的微波延迟线具有体积小、重量轻、插损小等优点,这是利用声表面波、同轴线、静磁波或常规金属平面结构设计的延迟线所无法比拟的。这些优点对于减轻通信系统的重量和缩小体积都是非常有利的。 - However , the msw - based mo devices haven ’ t still been applied extensively up to now because of low bragg diffraction efficiency . the generation and propagation characteristics of magnetostatic forward volume waves ( msfvws ) under nonuniform bias magnetic field and the bragg diffraction efficiency of gows with the msfvws are theoretically studied in this paper
本论文主要从理论上研究不均匀场中静磁正向体波( msfvw )的激发与传播特性,以及不均匀偏置磁场在提高静磁波对导波光的bragg衍射效率方面所起的作用。 - The influence of msfvw bandwidth on the diffraction efficiency is also considered . for the nonuniform bias magnetic field of u - type parabola profile , when the msw frequency is less than the cut - off frequency at the edge of mo film , the effective mo interaction length reduces . the edge cut - off frequency is determined by the maximum of the nonuniform field
对于抛物型分布(开口向上)的偏置磁场,当激发静磁波的rf频率小于边缘截止频率时,磁光作用的有效长度减小(与静磁波频率有关) ;边缘截止频率由不均匀磁场的最大值决定,静磁波的下限截止频率由不均匀场的最小值确定。 - In magneto - optic ( mo ) waveguids , the interaction between msws and guided optical waves ( gows ) can lead to the bragg diffraction of the gows . the resulting many new devices , such as mo modulator , optical switching , scanning , frequency spectrum analyzers , can be developed with applications to optical communication and optical information processing
在磁光波导中,静磁波与导波光相互作用可导致导波光的bragg衍射,利用这一原理,可做成磁光调制器、光开关、扫描仪、频谱分析仪等新型磁光bragg器件,并在光通信和光信息处理等领域有着十分广阔的应用前景,引起人们越来越多的关注。
