Simulation of Electromagnetic Scattering with Stationary or Accelerating Targets

The scattering of electromagnetic waves by an obstacle is analyzed through a set of partial differential equations combining the Maxwell’s model with the mechanics of fluids. Solitary type EM waves, having com-pact support, may easily be modeled in this context since they turn out to be explicit solutions. From the numerical viewpoint, the interaction of these waves with a material body is examined. Computations are carried out via a parallel high-order finite-differences code. Due to the presence of a gradient of pressure in the model equations, waves hitting the obstacle may impart acceleration to it. Some explicative 2D dynamical configu-rations are then studied, enabling the study of photon-particle iterations through classical arguments
