Pulse propagating

Description

The pulse propagates through a homogeneous medium in a rectilinear way:

Transmitted and reflected pulse

Description

The pulse is partially transmitted and reflected at the interface where the speed of propagation undergoes a change:

Transmission factor

Description

The transmission factor

$ T_{12} =\displaystyle\frac{2\sqrt{ Z_1 Z_2 }}{ Z_1 + Z_2 }$



can be plotted as a function of the ratio of the impedance in the medium that is transmitted divided by the impedance of the medium from which it comes:

Reflection factor

Description

The reflection factor

$ R_{12} =\displaystyle\frac{ Z_1 - Z_2 }{ Z_1 + Z_2 }$



can be plotted as a function of the ratio of the impedance in the medium that is transmitted divided by the impedance of the medium from which it comes:
