Parameters

Label - A unique name that identifies the attribute. (IAttribute/Label)

Color - Color used on objects to which this attribute is applied. (IAttribute/Color)

Number - Index of port. Must be non-zero and contiguous. Can be negative for differential ports. (IRFPort/Number)

Type - Type of port. (IRFPort/Type)

  • Wave

  • Lumped

Impedance (Real) - [IMPEDANCE] – Real part of the renormalization impedance. Ratio of tangential electric field to tangential magnetic field is equal to this value. (IRFPort/ImpedanceReal)

Impedance (Imaginary) - [IMPEDANCE] – Imaginary part of the renormalization impedance. (IRFPort/ImpedanceImaginary)

Lumped Only/Integration Path Count - Number of integration paths to use in port voltage calculations. Only used for lumped ports. (IRFPort/IntegrationPathCount)

Wave Only/Reference Plane Shift - [LENGTH] – Reference plane de-embedding distance. A positive value moves from the port "into" the structure. Only used for wave ports. (IRFPort/WaveDeembedDistance)

Wave Only/Number of Modes - Number of modes to extract at this port. Each mode is treated as a separate excitation and therefore has a row/column in the results S-parameter matrix. Only used for wave ports. (IRFPort/WaveNumberOfModes)

Wave Only/Manual Normalization Sample Point - If False, the simulator automatically computes a location on the port that is where the port electric fields are sampled to allow orientation and handling of mode degeneracies. If True, you can specify this location. Only used for wave ports. (IRFPort/WaveUseNormalizationSample)

Wave Only/Normalization Sample Point - [LENGTH] – Location on the port that is where the port electric fields are sampled to allow orientation and handling of mode degeneracies. Only used for wave ports. (IRFPort/WaveNormalizationSample)

Wave Only/Manual Orientation Up Vector - If False, the simulator automatically computes a vector on the port used to force the first mode of a degenerate set of modes on the port to have its electric field point in a given direction. If True, you can specify this vector. Only used for wave ports. (IRFPort/WaveUseOrientationUp)

Wave Only/Orientation Up Vector - Used to force the first mode of a degenerate set of modes on the port to have its electric field point in a given direction. Only used for wave ports. (IRFPort/WaveOrientationUp)

Excitation Amplitude/Type - Type of port excitation for field normalizations. For details see Fields. (IRFPort/AmplitudeType)

  • Power

  • Voltage

Excitation Amplitude/Power - [POWER] – Fields are normalized to produce this power on the port. Only visible if Excitation Amplitude/Type is Power. (IRFPort/AmplitudePower)

Excitation Amplitude/Voltage - [VOLTAGE] – Fields are normalized to produce this voltage on the port. Only visible if Excitation Amplitude/Type is Voltage. (IRFPort/AmplitudeVoltage)

Excitation Amplitude/Termination - This port's termination type, as it appears in the fields associated with other ports. (IRFPort/AmplitudeTerminationType)

  • Matched - This port appears as a matched load in other ports' fields.

  • Open - This port appears with infinite impedance, so fields associated with other ports show no current through this port.

  • Short - This port appears with zero impedance, so fields associated with other ports show zero voltage across this port.
