A definition is an object with no impact on a simulation unless it is assigned to a part, excitation, or sensor. Once that association is made, it determines the electromagnetic behavior of the parent object.

Material Definitions

A material definition provides the electromagnetic properties for a part. Once added to a project, a material definition is assigned to a part by either clicking and dragging it, or through the part's right-click menu.

Dispersive Material Calculator
Fit a Debye-Drude material to measured data.
Debye-Drude Material
Electric dispersive material definition.
Nondispersive Material
Isotropic material definition with constant properties versus frequency.
Surface Conductivity Correction
Maintain the surface impedance for a metal.

Circuit Component Definitions

A circuit component definition provides the lumped definition for a circuit component excitation. The excitation specifies the location in space, while the definition determines its behavior.

Diode
Model the nonlinear current-voltage curve of a PN junction.
Feed
Define a voltage or current source.
Netlist Component
Define a circuit component as a SPICE model.
Nonlinear Capacitor
Apply nonlinear behavior to a component.
Passive Load
Create an RLC component with no source.
Photoconductive Semiconductor Switch
Define a light-enabled switch.
Switch
Add opening and closing switches.

Sensor Definitions

A sensor definition is associated with a near-field sensor. The sensor specifies the location in space where the data is saved, and the definition determines which data to save.

Dielectric Breakdown Sensor Definition
Set the time sampling range to detect breakdown.
Point Sensor Definition
Set the time-domain data to collect for a point sensor.
Solid Sensor Definition
Set which data to collect in a 3-D volume.
Surface Current Sensor Definition
Request surface current output as a function of time or frequency.
Surface Sensor Definition
Set which data to collect on a 2-D surface.

Waveform Definitions

A waveform definition specifies the time-domain signal and frequency-domain content that is input into the simulation space through a feed definition, waveguide excitation, or plane wave excitation.

User Defined Waveform
Create a custom waveform definition.
Waveform Editor
Define an excitation's time- and frequency-domain content.
