DielectricCatalog

Open the dielectric catalog.

dc = DielectricCatalog;
open(dc)

List the properties of the dielectric material 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 material Foam as a dielectric in a cavity antenna of height and spacing, 0.0060 m.

d = dielectric('Foam');
c = cavity('Height',0.0060,'Spacing',0.0060,'Substrate',d)

c = 
  cavity with properties:

            Exciter: [1x1 dipole]
          Substrate: [1x1 dielectric]
             Length: 0.2000
              Width: 0.2000
             Height: 0.0060
            Spacing: 0.0060
    EnableProbeFeed: 0
          Conductor: [1x1 metal]
               Tilt: 0
           TiltAxis: [1 0 0]
               Load: [1x1 lumpedElement]

Open the dielectric catalog by using openDielectric Catalog function.To add a new material to the dielectric catalog, click on the row addition icon.

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

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

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