    Open the metal catalog.

    mc = MetalCatalog;
open(mc)

    Figure Metal Materials contains objects of type uimenu, uitoolbar, uitable.

    List the properties of the metal material Aluminium.

    s = find(mc,'Aluminium')
    s = struct with fields:
            Name: 'Aluminium'
    Conductivity: 37700000
       Thickness: 30
           Units: 'mil'
        Comments: ''

    Use the above metal in a coplanar waveguide.

    m = metal('Aluminium');
waveguide = coplanarWaveguide('Conductor',m)
    waveguide = 
  coplanarWaveguide with properties:

              Length: 0.0231
               Width: 0.0039
             Spacing: 2.0000e-04

           Substrate: [1×1 dielectric]
           Conductor: [1×1 metal]
          IsShielded: 0

    View the waveguide using show function.

    figure;
show(waveguide)

    Figure contains an axes object. The axes object with title coplanarWaveguide element, xlabel x (mm), ylabel y (mm) contains 48 objects of type patch, surface. These objects represent Aluminium, feed, Teflon.

    Figure Dielectric Materials contains objects of type uimenu, uitoolbar, uitable.

    List the properties of the dielectric substrate Foam.

    s = find(dc,'Foam')
    s = struct with fields:
                     Name: 'Foam'
    Relative_Permittivity: 1.0300

    Use the substrate Foam in coplanar waveguide.

    d = dielectric('Foam');
waveguide = coplanarWaveguide('Substrate',d)
    waveguide = 
  coplanarWaveguide with properties:

              Length: 0.0231
