DielectricCatalog

Catalog of dielectric materials

    Description

    Use the DielectricCatalog to explore the types of dielectrics and their properties.

    Creation

    Description

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

    • To open the dielectric catalog, use the open function.

    • To see the properties of a dielectric material from the dielectric catalog, use the find function.

    example

    Examples

    collapse all

    Open the dielectric catalog.

    dc = DielectricCatalog;
    open(dc)

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

    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: [1×1 dipole]
              Substrate: [1×1 dielectric]
                 Length: 0.2000
                  Width: 0.2000
                 Height: 0.0060
                Spacing: 0.0060
        EnableProbeFeed: 0
              Conductor: [1×1 metal]
                   Tilt: 0
               TiltAxis: [1 0 0]
                   Load: [1×1 lumpedElement]
    
    
    show(c)

    Figure Dielectric Materials contains an axes object. The axes object with title cavity antenna element, xlabel x (mm), ylabel y (mm) contains 6 objects of type patch, surface. These objects represent PEC, feed, Foam.

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

    dielectriccat_custom1_test.png

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

    dielectriccat_custom2_test.png

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

    dielectriccat_custom3_test.png

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