Domain Decomposition Methods for Time Harmonic Electromagnetic Waves With High Order Whitney Forms
Classically, the domain decomposition methods (DDMs) for time harmonic electromagnetic wave propagation problems make use of the standard, low order, Nedelec basis functions. This paper analyzes the convergence rate of DDM when higher order finite elements are used for both volume and interface discretizations, in particular when different orders are used in the volume and on the interfaces.
