电磁材料数据库(2024--04--11)

数据载体

  • 由于数据库的建立需要大量的手工录入,因此考虑采用Excel,拓展名为.xlsx
  • 数据库名称为eledata.xlsx
  • 数据库有两个sheet,分别是记录介电常数的eps和记录磁导率的mu.

数据标签

  • eps中数据标签含义

    • name of material 材料名称;

    • min relative permittivity (Re) 最小相对介电常数的实部;

    • min relative permittivity (Im) 最小相对介电常数的虚部,缺省为不存在;

    • max relative permittivity (Re) 最大相对介电常数的实部,缺省为不存在;

    • max relative permittivity (Im) 最大相对介电常数的虚部,缺省为不存在;

    • min working frequency(f, Hz) 测量时相应的最小工作频率,单位是赫兹(Hz);

    • max working frequency(f, Hz) 测量时相应的最大工作频率,单位是赫兹(Hz);

    • reference material 材料参数来源的参考资料.


  • mu中数据标签含义

    • name of material 材料名称;

    • min relative permeability (Re) 最小相对磁导率的实部;

    • min relative permeability (Im) 最小相对磁导率的虚部,缺省为不存在;

    • max relative permeability (Re) 最大相对磁导率的实部,缺省为不存在;

    • max relative permeability (Im) 最大相对磁导率的虚部,缺省为不存在;

    • min working frequency(f, Hz) 测量时相应的最小工作频率,单位是赫兹(Hz);

    • max working frequency(f, Hz) 测量时相应的最大工作频率,单位是赫兹(Hz);

    • reference material 材料参数来源的参考资料.

说明

  • 大多数材料给出的参数都是以图表形式给出,这里我们使用了软件 https://getdata-graph-digitizer.software.informer.com/ 获得材料的具体参数;
  • 对于相同名称材料,在不同频率下有不同材料参数,往往这种材料可以通过插值方法获得未知频率下的材料参数;
