The figure also shows — the value of the argument SigmaCond, — the value of the argument EpsilonR, — the value of the argument MuR and — the value of the argument LossTangent.

Syntax

Function call

coaxialtxline = txlineCoaxial() — creates a coaxial transmission line object with default properties.

coaxialtxline = txlineCoaxial(Name=Value) — sets properties specified by one or more arguments of the type «name-value». Unspecified properties retain their default values.

Arguments

Input arguments «name-value»

Specify optional argument pairs as Name=Value, where Name — the name of the argument, and Value — the appropriate value. You can specify multiple pairs «name-value».

Example: coaxialtxline = txlineCoaxial(OuterRadius = 0.0046) creates a coaxial transmission line with an external radius 0.0046 m.
