Abstract: 
A popular approach for treating time-harmonicMaxwell problems in open domains is the tech-nique of complex scaling. Thereby a complexcoordinate stretching is applied leading to expo-nentially decreasing outgoing solutions. Usuallya perfectly matched layer is generated by trun-cating the domain and discretizing the problemin the bounded layer with finite elements. Inour work we present a method based on com-plex scaling that omits truncation by the useof infinite elements. These infinite elements arestraightforward to use and lead to super-algebraicconvergence with respect to the number of un-knowns in propagation direction. Moreover, theyare stable, i.e. the condition numbers of the dis-cretization matrices are small.
