Catalog of metals

Since R2021a



    mc = MetalCatalog creates an object handle for the metal catalog.

    • To open the metal catalog, use open(mc)

    • To see the properties of a metal from the metal catalog, use s = find(mc,name).

    Open the metal catalog.

    mc = MetalCatalog;

    List the properties of the metal material Brass.

    s = find(mc,"Brass")
    s = struct with fields:
                Name: 'Brass'
        Conductivity: 15900000
           Thickness: 0.6800
               Units: 'mm'
            Comments: ''

    Use the material Brass as a metal in a corrugated horn antenna.

    m = metal("Brass");
    ant = hornCorrugated(Conductor=m)
    ant = 
      hornCorrugated with properties:

                          Load: [1x1 lumpedElement]

    View the antenna using show function.


    Open the metal catalog using MetalCatalog function. To add a new material to the metal catalog, click on the row addition icon.


    A duplicate record of the metal material appears below the selected row.


    You can change the record by setting a desired name, conductivity and thickness of the material to customize.


    You can access the new added metal material by using metal object.
