Application of the fast Fourier transform to infinite periodic structures

Application of the fast Fourier transform to infinite periodic structures

The fast Fourier transform is applied to accelerate the computation of the behavior of elements in infinite periodic arrays. Results of an implementation of this technique for general 3-D elements in an arbitrary planar lattice are presented. This technique was incorporated into the Finite Element R...

Beschreibung
Zusammenfassung:The fast Fourier transform is applied to accelerate the computation of the behavior of elements in infinite periodic arrays. Results of an implementation of this technique for general 3-D elements in an arbitrary planar lattice are presented. This technique was incorporated into the Finite Element Radiation Model (FERM) method of moments code.< >
