Examples

Use Metal Catalog to Design Corrugated Horn Antenna

Open the metal catalog.

mc = MetalCatalog;
open(mc)

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:

Addition of Custom metal in Metal Catalog

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.
