find

View properties of metals or dielectrics

Since R2021a

Syntax

s = find(catalog,name)

Description

s = find(catalog,name) shows the properties of name from the metal or dielectric catalog catalog.

Examples

Use Metal Catalog to Design Coplanar Waveguide

Open the metal catalog.

mc = MetalCatalog;
open(mc)

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
          ViaSpacing: [0.0011 0.0070]
         ViaDiameter: 5.0000e-04
              Height: 0.0016
    GroundPlaneWidth: 0.0300
           Substrate: [1×1 dielectric]
           Conductor: [1×1 metal]
          IsShielded: 0

Use Dielectric Catalog to Design Coplanar Waveguide

Open the dielectric catalog.

dc = DielectricCatalog;
open(dc)

List the properties of the dielectric substrate Foam.

s = find(dc,'Foam')

s = struct with fields:
                     Name: 'Foam'
    Relative_Permittivity: 1.0300
             Loss_Tangent: 1.5000e-04
                Frequency: 50000000
                 Comments: ''

Use the substrate Foam in coplanar waveguide.

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

waveguide = 
  coplanarWaveguide with properties:

              Length: 0.0231
               Width: 0.0039
             Spacing: 2.0000e-04
          ViaSpacing: [0.0011 0.0070]
         ViaDiameter: 5.0000e-04
              Height: 0.0016
    GroundPlaneWidth: 0.0300
           Substrate: [1×1 dielectric]
           Conductor: [1×1 metal]
          IsShielded: 0
