Summary
| Description |
English: Simulation showing the formation of the Arago spot in the pulse scalar wave (Dirichlet boundary condition). The radius of the obstacle equals 25 central wavelengths of the pulse.
The scale is linear with respect to the energy (square of the absolute value of the amplitude). The simulation is done by placing 150 families of Green function sources across the obstacle (i-th family along the circle of radius R(i-1)/150). The amplitudes are chosen from fitting the condition "field near the obstacle = 0". |
