Lumped Element
Use a Lumped Element node to mimic the insertion of a capacitor, inductor, or general impedance between two metallic boundaries. A Lumped Element condition is a passive lumped port boundary condition which cannot be used as a source. Unlike a Lumped Port, it does not generate S-parameters. The sign of the current and power of a Lumped Element is opposite to that of a Lumped Port.
It can only be applied on boundaries that extend between two metallic boundaries — that is, boundaries where Perfect Electric Conductor, Impedance Boundary, or Transition Boundary (Electromagnetic Waves, Frequency Domain interface only) conditions apply — separated by a distance much smaller than the wavelength.
Lumped Element Properties
Enter a unique Lumped element name. See Lumped Port for the rest of the settings.
Settings
Select a Lumped element device User defined (the default), Inductor, Capacitor, Parallel LC, Series LC, Parallel RLC, or Series RLC. Inductor, Capacitor, Parallel LC, Series LC, Parallel RLC, and Series RLC are available only in the frequency domain study type.
For User defined enter a Lumped element impedance Zelement (SI unit: Ω). The default is 50 Ω.
For Inductor, Parallel LC, Series LC, Parallel RLC, or Series RLC enter a Lumped element inductance Lelement (SI unit: H). The default is 1 nH.
For Capacitor, Parallel LC, Series LC, Parallel RLC, or Series RLC enter a Lumped element capacitance Celement (SI unit: F). The default is 1 pF.
For Parallel RLC, or Series RLC enter a Lumped element resistance Relement (SI unit: Ω). The default is 50 Ω.
Calculator
Enter a Relative permittivity (default is 1) for the dielectric material between the coaxial inner and outer conductor and then click the Compute Coaxial Line Impedance button to compute the impedance for the coaxial lumped element. The result is displayed in the Messages window.
