Reflector antennas [1] are devices that are widely use for satellite communication. The life length of such devices depends highly on the fatigue due to the energy consumption for the signal emission. Thus, one of the goals of the optimal design of an antenna is to improve the productivity of systems designed for a given task, for a fixed input power. A(More)
The numerical approximation of the solution of a PDE is generally obtained with the resolution of a system of equations (linear or nonlinear) that comes from the discretization of the PDE on a given domain. The resulting system may be stiff, partly due to the approximation of differential operators, and therefore makes the iterative methods harder to(More)
