The problem of accelerating the calculation of the periodic Green's function in free space is addressed here. Periodicity is considered both along one axis and along two, generally skew, axes. A systematic review of the existing methods is first presented, with the aim of characterizing their capability to treat the case of a complex phase shift between unit cells, necessary for the study of complex modes in periodic structures. The case of a 1-D periodic array of dipoles is treated in detail. Comparisons among the various acceleration methods are performed, thus providing fundamental information on their actual numerical efficiency.

Abstract

The problem of accelerating the calculation of the periodic Green's function in free space is addressed here. Periodicity is considered both along one axis and along two, generally skew, axes. A systematic review of the existing methods is first presented, with the aim of characterizing their capability to treat the case of a complex phase shift between unit cells, necessary for the study of complex modes in periodic structures. The case of a 1-D periodic array of dipoles is treated in detail. Comparisons among the various acceleration methods are performed, thus providing fundamental information on their actual numerical efficiency.
