Syntax

dc = DielectricCatalog

Description

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).

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

List the properties of the dielectric substrate Foam.

s = find(dc,'Foam')

s = struct with fields:
                     Name: 'Foam'
    Relative_Permittivity: 1.0300

Use the substrate Foam in coplanar waveguide.

d = dielectric('Foam');
waveguide = coplanarWaveguide('Substrate',d)

waveguide =
