This simulates the reflection coefficient either at a load on a cable, or at the junction with another cable. The load can be real or complex and can be adjusted to match or mismatch the cable. The simulation also allows the reflection coefficient to be visualised as a phasor diagram at varying distances from the load. This underlies the principle of stub-matching
