Er is the permittivity of the substrate material relative to the permittivity of free space ε0 = 8.854 x 10-12 F/M
Tand is the dielectric loss tangent of the substrate material: Tand = εr″/εr′ where εr = εr′ -jεr″
Rho is the bulk resistivity of conductor metal normalized to copper (to 1.7 x 10 -8 Ω*m)
Actual metal bulk resistivity = Rho*1.7 x 10 -8 Ω*m.
B and T are cross sectional dimensional variables given in default length units.
In a schematic that contains stripline elements, at least one instance of this element must exist. The Name parameter provides a unique identifier for each instance of SSUB. The stripline elements have a SSUB parameter that indicates which SSUB element to use.
Note that you can also add this substrate to the Global Definitions window and then reference the material from any schematic.
This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
