进入HFSS创建好新工程，然后依次选择“Tools”>"Edit Configuride Libraries">"Materials"，如图所示
会跳出“Edit Libraries”窗口，选择下方的“Add Material”去添加新材料

然后会跳出“View/Edit Libraries”窗口，你要根据你的需要对这些参数进行修改

下图中箭头所指的是材料的名称，你可以对它进行修改，下面的参数我能用到的是“Relative Permittivity”和“Dielectric Loss Tangent”

“Relative Permittivity”指的是材质的相对介电常数

“Dielectric Loss Tangent”指的是材质的损耗正切值
