dielectric
Catalog of dielectric materials
dc = DielectricCatalog
dc = DielectricCatalog creates an object for the dielectric catalog.
dc
To open the dielectric catalog, use open(dc)
open(dc)
To know the properties of a dielectric material from the dielectric catalog, use s = find(dc,name).
s = find(dc,name)

Open the dielectric catalog.
dc = DielectricCatalog; open(dc)
List the properties of the dielectric material Foam.
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.
openDielectric Catalog
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.
"Air"
Name of a dielectric material from the dielectric catalog, specified as a character vector.
Example: "FR4"
"FR4"
Data Types: string
string
Dielectric catalog, specified as an object.
Data Types: char
char
Dielectric catalog, returned as an object.
Parameters of a dielectric material from the dielectric catalog, returned as a structure.
