getz0

Characteristic impedance of transmission line object

Syntax

z0 = getz0(h)

Description

z0 = getz0(h) returns a scalar or vector, z0, that represents the characteristic impedance(s) of circuit object h. The object h can be rfckt.txline, rfckt.rlcgline, rfckt.twowire, rfckt.parallelplate, rfckt.coaxial, rfckt.microstrip, or rfckt.cpw.

Examples

Create and analyze a two-wire network object.

 tx1=rfckt.twowire('Radius',7.5e-4)
 analyze(tx1,1.9e9)
tx1 = 

   rfckt.twowire with properties:

            Radius: 7.5000e-04
        Separation: 0.0016
               MuR: 1
          EpsilonR: 2.3000
       LossTangent: 0
         SigmaCond: Inf
        LineLength: 0.0100
          StubMode: 'NotAStub'
       Termination: 'NotApplicable'
             nPort: 2
    AnalyzedResult: []
              Name: 'Two-Wire Transmission Line'

   rfckt.twowire with properties:

            Radius: 7.5000e-04
        Separation: 0.0016
               MuR: 1

        LineLength: 0.0100
          StubMode: 'NotAStub'
       Termination: 'NotApplicable'
             nPort: 2
    AnalyzedResult: [1x1 rfdata.data]
              Name: 'Two-Wire Transmission Line'

Find the Z0 of the two-wire object.

 z0 = getz0(tx1)
