3d Printed Lattices with Spatially Variant Self-collimation
In this work, results are given for controlling waves arbitrarily inside a lattice with spatially variant self-collimation. To demonstrate the concept, an unguided beam was made to flow around a 90◦ bend without scattering due to the bend or the spatial variance. Control of the field was achieved by spatially varying the orientation of the unit cells throughout a self-collimating photonic cryst...
متن کامل3D-Printed Self-Folding Electronics.
Self-transforming structures are gaining prominence due to their general ability to adopt programmed shapes each tailored for specific functions. Composites that self-fold have so far relied on using the stimuli-responsive mechanisms focusing on reversible shape change. Integrating additional functions within these composites can rapidly enhance their practical applicability; however, this rema...
متن کاملBroadband diffraction management and self-collimation of white light in photonic lattices.
We introduce periodic photonic structures where the strength of diffraction can be managed in a very broad frequency range. We show how to design arrays of curved waveguides where light beams experience wavelength-independent normal, anomalous, or zero diffraction. Our results suggest opportunities for efficient self-collimation, focusing, and reshaping of beams produced by white-light and supe...
متن کاملSpatially Variant GRAPPA
E. G. Kholmovski, D. L. Parker Utah Center for Advanced Imaging Research, Department of Radiology, University of Utah, Salt Lake City, Utah, United States Introduction: GRAPPA [1], a widely used technique for parallel MRI (P-MRI), has serious limitations for image reconstruction from highly undersampled data. Recently, two algorithms, GARSE [2] and MCMLI [3], have been proposed to resolve this ...
