In this paper, we have proposed a method derived from a Nitsche type approach to handle boundary and transmission
conditions in some partial differential equations. Two examples of applications have been given. The first one
was concerned with the Maxwell equations in singular domains. We have mainly considered the static Maxwell equations,
the difficulty coming from singular domains being mainly static. However, the extension to the time-dependent
Maxwell equations is straightforward. A numerical example was given in two dimensions as a first attempt to show
the efficiency of the proposed method. In particular, we show the ability of this approach to approximate a singular
behavior of the Maxwell equations solution in a non-convex geometry. In the second application, we considered the
Navier Lame equations in two dimensional cracked plate for dissimilar materials. We presented a new concept of
handling the interface conditions in the case of interface crack existence in dissimilar materials. A numerical example
was also given in two dimensions for a dissimilar material made of 4 layers. It illustrates the ability of the method to
simulate a crack in dissimilar elastic material. Hence, the method seems promising for instance to compute the stress
fields in the case of different materials, like elasto-plastic, viscoelastic and hyper elastic materials.
