Linux/uClinux/Unix编程 DDA使用教程
DDSCAT 7.3 is a freely available open-source Fortran-90 software package applying the “discrete
dipole approximation” (DDA) to calculate scattering and absorption of electromagnetic waves by targets
with arbitrary geometries and complex refractive index. The targets may be isolated entities (e.g., ...
书籍 Modern+Receiver+Front-Ends
In recent years, the research and developments in the area of RF and microwave
technologies have progressed significantly due to the growing demand for applica-
bility in wireless communication technologies. Starting from 1992, wireless com-
munication technologies have become quite mature. In the m ...
技术资料 电磁场
在电磁学里，电磁场（electromagnetic field）是一种由带电物体产生的一种物理场。处于电磁场的带电物体会感受到电磁场的作用力。电磁场与带电物体（电荷或电流）之间的相互作用可以用麦克斯韦方程和洛伦兹力定律来描述
技术资料 EMC基础培训资料
EMC即电磁兼容，EMC是英文Electromagnetic Compatibility的缩
写。在我们生活、工作的环境中，时时刻刻都存在着各种各样的电磁能量，这些电磁能量可能会使电子设备的运行产生不应有的响应。我们把电磁能量对电子设备的这种影响称之为电磁干扰。电磁兼容就是
研究电磁干扰的一门技术，对电磁兼容通俗的解释是： ...
