This is an electrostatic field package for GNU Octave. It contains functions that can calculate capacitance matrix of metal blocks, inductance matrix of metal bounds, impedance matrix of metal dipoles (antennas), and so on.
GDS visualization and parallelized capacitance extraction
Project CAPLET is a capacitance extraction toolkit that extract capacitance at field-solver accuracy. CAPLET can directly handle GDS2 layout files into capacitance matrices in both GUI and command line interfaces. The internal extraction algorithm is specialized for VLSI interconnect structures but not exclusively, as long as the structure is of Manhattan geometry and embedded in a uniform dielectric material.
Electric Behaviour of Crystals and Pierce Crystal Oscillators
...Crystal parameters can be freely choosen. Display is spectrum analyzer-like and shows the amplitude/phase and/or a Nyquist diagram. Crystals can be series resonant or with load capacitance. Adding of spurious resonances is possible.
A GTK+/Gnome2 graphical front end for the IW3HEV Vector Network Analyzer, also has a signal generator, and It displays graphicaly SWR, Phase, Return Loss, X impedance, Serial resistance, |Z| Impedanze, and Inductance, and capacitance.
