Abstract: Water-wave diffractions caused by three-dimensional (3D) periodic rectangular blocks are analytically modeled with a Fourier modal analysis method using full-linear potential theory. The boundary conditions in the dimension of periodic extent are conjugated into the… read more here.

Abstract: This study presents a novel dissipative Fourier modal analysis (DFMA) method for modeling wave diffraction in periodic structures. Unlike traditional methods, which limit analyses to a single diffraction order or dispersion mode, DFMA handles multiple… read more here.

DOI: 10.1107/s1600576725000615
Abstract: We report a rigorous method for calculating the interaction of neutron waves with a periodic potential structure. In earlier work, several assumptions and simplifications were used in methods describing the diffraction of neutron waves from… read more here.
