Getting Started with 2D Extractor

2D Extractor is an interactive software package that can electrically characterize two-dimensional structures, such as transmission lines and connector cross-sections. By modeling the field patterns in a single cross-section, 2D Extractor can analyze field patterns in an entire device.

2D Extractor can:

• Compute capacitance and inductance for lossless transmission structures, and compute impedance and admittance matrices for lossy transmission structures.
• Compute the characteristic impedance of the transmission line structure, its modal velocities, and its modal transformation matrices.
• Compute forward and backward crosstalk coefficients.
• Display field patterns in a transmission line given a particular distribution of charge, potential, or current.
• Export a SPICE equivalent circuit to a file that can be read into any other software package that uses a compatible version of SPICE.
• Perform variational analyses of designs by varying solution frequencies, model dimensions, material properties, and other transmission line parameters.

You can draw or import a geometric model of your structure's cross-section into 2D Extractor and then specify:

• All relevant material characteristics
• Boundary conditions describing field behavior
• Sources of charge, current, or voltage
• Solution criteria

After 2D Extractor computes the requested circuit parameters, you can export circuit equivalents, and view and analyze the computed matrices or fields.
