Catalog of dielectric materials



dc = DielectricCatalog creates an object handle for the dielectric catalog.

  • To open the dielectric catalog, use open(dc)

  • To see the properties of a dielectric material from the dielectric catalog, use s = find(dc,name).

Open the dielectric catalog.

dc = DielectricCatalog;

{"String":"Figure Dielectric Materials contains objects of type uimenu, uitoolbar, uitable.","Tex":[],"LaTex":[]}

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

           Substrate: [1x1 dielectric]
           Conductor: [1x1 metal]

View the waveguide.


Figure contains an axes object. The axes object with title coplanarWaveguide element contains 48 objects of type patch, surface. These objects represent PEC, feed, Foam.
