QUCS is a freeware circuit simulator that supports S-parameter analysis, among other types. It is available for Windows, Linux and OSX operating systems, with varying levels of support from the community.

A useful system-level overview of Microwave and RF concepts from the author of the well known reference on RF circuit design.

This interactive demo allows you to experiment with waves and reflections under various conditions. The demonstration shows mechanical waves but the concepts are analogous to EM waves on transmission lines.

Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open.
