Circuit synthesis

• Eletsim - Generates tables of passive filters. Windows version.
• Other synthesis programs (HK, Ladder, Cheby, Elliptic), Windows versions.
• Other synthesis programs (Old DOS versions.).
• Match1 - Designs LC impedance matching networks. Windows.
• FDSZ - Design of continuous and discrete time filters in biquad cascade. Windows.

Electromagnetism

• Inca - Calculates mutual inductances and coupling coefficients between two solenoidal, flat, or conical coils,and makes several calculations of capacitances, potential, and electric field. Version 2.1 - 14/6/2015.This document explains how it performs some inductance calculations, and this explains some capacitance calculations.
• Canton - Simulates sets of "pith balls", spheres suspended from strings, and general tri-dimensional capacitances.

Electrostatic generators

• WMD - Wimshurst machine designer. Determines the dimension of the sectors, and predicts spark length and output current. Works also for sectorless machines (Bonetti machines). Version 1.3 - 10/7/2001.
• ElCal - Calculations about Van de Graaff generators, Leyden jars, spark gaps, pith balls, etc.

Multiple resonance networks (generalized Tesla coils and induction coils)

• TeslaSim - Designs and simulates the energy transfer in classical Tesla coils, computing exact waveforms using a simple lumped model. Version 2.7b - 14/04/2003 (DOS).
• MagSim - Designs and simulates (with the help of TeslaSim) Tesla magnifiers, or triple resonance networks with a transformer. Version 1.2 - 26/04/2003.
• MultiRes - Designs low-pass transformerless multiple resonance networks and plots waveforms.Version 1.6- 14/02/2003.
• MresHp - Designs high-pass and some band-pass multiple resonance networks, and plots waveforms. Version 1.5a - 7/10/2003.
• Mrn4 - Designs several 4th-order multiple resonance networks, including Tesla coils and induction coils, and plots waveforms. Version 1.7 - 6/5/2003.

These programs can design lossless systems, optimize them in the presence of losses (resistances in series with the coils) or other conditions, and plot or save voltage and current waveforms during the energy transfer transient.
• Drsstcd. Designs a "double resonance solid-state Tesla coil", as an impedance matching network or as a multiple resonance network using the zero-state response.
• Trsstcd. Designs a "triple resonance solid-state Tesla coil", as a multiple resonance network using the zero-state response.
  
• A simple simulator for a "double resonance solid-state Tesla coil", or for a conventional Tesla coil: source code in C.
• A similar simulator, for a "triple resonance solid-state Tesla coil", or for a conventional Tesla magnifier: source code in C.
