Summary: In [COMPEL 19, No. 3, 913–931 (2000; Zbl 0994.78021)] the article the second author developed a new finite volume scheme for the resolution of the heterogeneous Maxwell equations in three dimensions. The scheme is based on a leapfrog time discretization and involves a centered flux formula for discretization in space. Numerical tests have shown the performance of the method, namely on unstructured grids. In this paper, we will present some recent convergence results in \(L^2\) in the case of unstructured grids which satisfy an appropriate “aspect condition”. This condition will be dicussed and illustrated by some numerical results.
