Wcalc is a tool for the analysis and synthesis of electronic components. Some of the models include coupled microstrip lines, single layer air core solenoid inductors, etc. Wcalc can analyze the electrical parameters based on the physical dimensions a
Demonstrates quantal two-slit Fresnel interference patterns.
InterferenceSimulator is a program demonstrating quantal two-slit Fresnel interference patterns with one, the other, or both slits open. A magnetic flux situated between the two slits allows demonstration of the Aharonov–Bohm effect. Simulations with short de Broglie wavelengths illustrate the classical limit of quantum mechanics. Because of the universality of wave phenomena, this program can also demonstrate the geometrical-optics limit of wave optics for small wavelengths.
MesoRD is a stochastic and deterministic simulator of coupled chemical reactions and diffusions in space.
ChemVisio is software which might be useful for educational purposes (non-organic chemistry, crystallography etc.). It might be a good visualization support for all people who need better illustrations than that you could see in books.
