DielectricCatalog
Catalog of dielectric materials
Syntax
Description
Examples
Use Dielectric Catalog Element in Cavity
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]

Addition of Custom dielectric
Material in Dielectric Catalog
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.
Input Arguments
