Analysis of the microstructures (“rosettes”) in the superposition of periodic layers
Journal of Electronic Imaging, 2002 Superpositions of periodic dot screens are largely used in electronic imaging in the field of color printing. In such superpo- sitions the interaction between the superposed layers may cause new structures to appear which did not exist in any of the original layers: macrostructures (also known as moirepatterns) and micro- structures (also known as ...

Strayfield calculation for micromagnetic simulations using true periodic boundary conditions
Scientific Reports, 2021 We present methods for calculating the strayfield in finite element and finite difference micromagnetic simulations using true periodic boundary conditions. In contrast to pseudo periodic boundary conditions, which are widely used in micromagnetic codes,

On the optimization of non periodic homogenized microstructures [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 1997 An analytic study of the optimization of a domain is presented, with respect to a broad class of admissible holes (microstructures) in order to maximize or minimize some functional. The authors define the class of admissible perforations to be used with the homogenization technique and show how to compute the differential of both the homogenized ...

A Periodic Systems Toolbox for MATLAB [PDF]
, 2005 The recently developed Periodic Systems Toolbox for MATLAB is described. The basic approach to develop this toolbox was to exploit the powerful object manipulation features of MATLAB via flexible andfunctionally rich high level m-functions, while ...

Periodic microstructure in Saturn's rings A and B [PDF]
Geophysical Research Letters, 2007 Diffraction of coherent radio waves transmitted by the Cassini spacecraft at 0.94‐ and 3.6‐cm wavelengths indicates the presence of fine‐scale structure in Saturn's rings A and B, characterized by a periodic radial variation in optical depth. Interpretation of the observed spectral signature in terms of a simple diffraction grating model yields ...
