  In this paper, we advocate a novel spline-based isogeometric approach for
boundary elements and its efficient implementation. We compare solutions
obtained by both an isogeometric approach, and a classical parametric
higher-order approach via Raviart-Thomas elements to the solution of the
electric field integral equation; i.e., the solution to an electromagnetic
scattering problem, promising high convergence orders w.r.t. pointwise error.
We discuss both, the obtained accuracy per DOF, as well as the effort required
to solve the corresponding system iteratively, on three numerical examples of
varying complexity.
