This is a simulation of the time-domain analysis presented in:
"An Investigation and Simulation of the Time-Dependence of the Waves in a Single-Stub Matching Network", (Alan F. Murray, Brian W. Flynn and Tim Drysdale).
- Simulation - Excel
- Python code for a single-stub example
- Paper describing the method and the example above
Please note - these simulations work on a Windows machine. The slider controls etc can behave in a silly manner if you change resolution without rebooting your machine (eg by docking/undocking it or by using a data projector). This is a well-known "feature" of Excel(!) and it is cured by rebooting the computer plugged into whatever you do or do not want it plugged into.
