The Maxwell equations read:
where is the electric field,
the magnetic field,
the current density,
the speed of light,
density of electric charge,
the vacuum permeability and
the vacuum permittivity.
In the midst industrial notament in aeronautics, systems Products must verify certain standards such as the receipt an electromagnetic wave emitted by a radar does not cause the inefficassité of part or all of the hardware in the system.
Thus, the simulation of such situations can develop when or during the certification of a new product to test its reaction to such attacks.
Also note that the last two equations are actually initial conditions, since if we assume they are true at the moment then it can be deduced from the first two.
At $t=0s$, we suppose that
Suppose that and
i.e.
Differentiating the first of these two equations with respect to time, we get:
thanks to
So, for all ,
We deduce the same way the second equation, using the charge conservation equation :
