Abstract

A study of mechanisms to account for periodicity when modeling two-dimensional (2-D) structures with a hybrid finite-element boundary integral equation (FE-BIE) method is presented. These techniques are either based on the use of Green´s functions or on the application of the Floquet-Bloch theorem as a periodic boundary condition. The described formalism can be used to model very diverse problem geometries as is demonstrated by means of some typical examples. For these configurations, it is shown how an optimal choice can be made between the mechanisms that impose periodicity
