The parameters of the simulator are :

- Incident wave V
_{I}(t) propagates from the left to the right side of the screen and it is described by the following eqaution :

- Reflected Wave V
_{R}(t) propagates from left to right when the load is not matched to the propagation medium. The equation of V_{R}(t) is :

- The summation of both waves produces a stationary wave inside the propagation medium as it is show in the third figure in black.

Characteristics of the stationary wave

- The maxima of the stationary wave occurs when the incident wave V
_{I}(t) is in phase with the reflected wave V_{R}(t), the maximum is : E_{max}= V_{I,max}+ V_{R,max}. The minima of the wave occurs when the reflected wave V_{R}(t) is 180^{0}of of phase with V_{I}(t) : E_{min}= V_{I,max}- V_{R,max} - The is the parameter used to quantify the presence of the standing wave in the propagation medium. The eqaution used to describe the VSWR is given by :
__VSWR__Voltage Standing Wave Ratio.

- The distance between two consecutive peaks of the SW is given by the following expression :

With λ the wavelength of the incident or the reflected wave.
