=== Defining Embedded Object Sets ===
Embedded object sets represent short material insertions inside substrate layers. They can be metal or dielectric. Metallic embedded objects can be used to model vias, plated-through holes, shorting pins and interconnects. These are called PEC via sets. Embedded dielectric objects can be used to model air voids, thin films and material inserts in metamaterial structures. Embedded magnetic object are not currently supported by [[EM.Cube]]âs [[Planar Module]]. Embedded objects can be defined either from the Layer Stack-up Settings dialog or directly from the Navigation Treenavigation tree. In the former case, open Open the "Embedded Sets" tab of the stack-up dialog. This tab has a table that lists all the embedded object sets along with their material type, the host substrate layer, the host material and their height. To add a new object set, click the arrow symbol on the {{key|Insert}} button of the dialog and select one of the two options, '''PEC Via Set''' or '''Embedded Dielectric Set''', from the dropdown list. This opens up a new dialog where first you have to set the host layer of the new object set. A dropdown list labeled "'''Host Layer'''" gives a list of all the available finite substrate layers. You can also set the properties of the embedded object set, including its label, color and material properties. Keep in mind that you cannot control the height of embedded objects. Moreover, you cannot assign material properties to PEC via sets, while you can set values for the '''Permittivity'''(ε<sub>r</sub>) and '''Electric Conductivity'''(σ) of embedded dielectric sets. Vacuum is the default material choice.
{{Note|The height of an embedded object is always identical to the thickness of its host substrate layer.}}

Vacuum is the default material choice. You may use [[EM.Cube]]'s Material List for this purpose, which can be opened up by clicking the '''Material''' button. Once embedded object sets are added to the Embedded Sets table, you can edit their properties at any time by selecting their row and clicking the '''Edit''' button. [[File:PMOM21.png]] [[File:PMOM22.png]] Figure 2: The [[Planar Module]]'s PEC Via Set and Embedded Dielectric Set dialogs.

After a new To define an embedded object set has been defined and added to the Navigation Tree, it becomes the active trace. You are now ready to create geometrical objects in the new active trace. Remember that [[Planar Module]] does not allow you to draw 3D objects. The solid object buttons in the '''Object Toolbar''' are disabled to prevent you from doing so. Instead, you draw planar [[Surface Objects|surface objects]] as the cross section of embedded sets. [[EM.Cube]] extends these planar objects across their host layer automatically and displays them as wire-framenavigation tree, 3D extruded objects. Extrusion of embedded object sets happen after meshing and before every simulation. You can enforce this extrusion manually by right clicking -click on the '''Layer Stack-upEmbedded Object Sets''' item in the '''Computational DomainPhysical Structure''' section of the Navigation Tree navigation tree and selecting select either '''Update Planar StructureInsert New PEC Via Set...''' from or '''Insert New Embedded Dielectric Set...''' The respective New Embedded Object Set dialog opens up, where you can set the contextual menuproperties of the new object set. As soon as you close this dialog, it takes you to the Layer Stack-up Settings dialog, where you can verify the location of the new object set on the layer hierarchy.
