Certified Reduced Basis Methods and Output Bounds for the Harmonic Maxwell's Equations
We propose certified reduced basis methods for the efficient and reliable evaluation of a general output that is implicitly connected to a given parameterized input through the harmonic Maxwell’s equations. The truth approximation and the development of the reduced basis through a greedy approach is based on a discontinuous Galerkin approximation of the linear partial differential equation. The formulation allows the use of different approximation spaces for solving the primal and the dual truth approximation problems to respect the characteristics of both problem types, leading to an overall reduction in the off-line computational effort. The main features of the method are: i) rapid convergence on the entire set of parameters, ii) rigorous a posteriori error estimators for the output and iii) a parameter independent off-line phase and a computationally very efficient on-line phase to enable the rapid solution of manyquery problems arising in control, optimization, and design....
