可编程逻辑 计算FR4上的差分阻抗(PDF)
Calculation of the Differential Impedance of Tracks on FR4 substrates
There is a discrepancy between calculated and measured values of impedance for differential transmission lineson FR4. This is especially noticeable in the case of surface microstrip configurations. The anomaly is shown tobe due to ...

三维矢量有限元-矩量法电磁场分析程序。
EMAP5 is a full-wave electromagnetic field solver that combines the method of moments (MOM) with a vector finite element method (VFEM). It employs the finite element method (FEM) to analyze a dielectric volume, and employs the method of moments (MoM) to solve fo ...

择PCB板材必须在满足设计需求和可量产性及成本中间取得平衡点。设计需求包含电气和机构这两部分。通常在设计非常高速的PCB板子(大于GHz的频率)时这材质问题会比较重要。例如，现在常用的FR-4材质，在几个GHz的频率时的介质损(dielectric loss)会对信号衰减有很大的影响，可能就不合用。就电气而言，要注意介电常数(dielectr ...

When trying to extract information from SAR images, we need to distinguish
two types of image property. The more important is where properties of the
scene (e.g., its dielectric constant, its geometry, its motion, etc.) produce effects
in the image measurements or examination of the image then can ...
