The purpose of this thesis is the construction of numerical schemes for the simulation of acoustic and electromagnetic wave propagation phenomena based on arbitrary high order efficient conforming finite elements. In the case of the scalar wave equation we develop an algorithm which generalizes the construction of mass-lumped triangular lagrangian finite elements (cf. Cohen-Joly-Tordjmann) which leads to the determination of a new mass-lumped $P_6$ element. We also present a new family of partial mass-lumped finite elements. In the case of electromagnetic waves propagation, we present a conforming coupling method between rectangular finite edge elements (with mass-lumping) and triangular finite edge elements, which permits the optimisation ...
