Pass-Band Optimal Reconstruction on the Body-Centered Cubic Lattice
In this paper, a pass-band optimal reconstruction technique is adapted to the Body-Centered Cubic (BCC) lattice. In order to perform the frequencydomain preprocessing, we derive a practical Discrete Fourier Transform (DFT) for BCC-sampled data. In the discrete frequency domain our DFT provides a natural isotropic periodicity on a FaceCentered Cubic (FCC) pattern, unlike the previous method, whi...
متن کاملData Processing on the Body - Centered Cubic Lattice
The body-centered cubic (BCC) lattice is the optimal three-dimensional sampling lattice. Its optimality stems from the fact that its dual, the face-centered cubic (FCC) lattice, achieves the highest sphere-packing efficiency. In order to approximate a scalar-valued function from samples that reside on a BCC lattice, spline-like compact kernels have been recently proposed. The lattice translates...
متن کاملPhotonic band gaps of three-dimensional face-centered cubic lattices
Using the photonic analogue of the Korringa-Kohn-Rostocker (KKR) method, the spectrum of electromagnetic waves in a three-dimensional fcc lattice of homogeneous dielectric spheres with various dielectric contrast is analyzed. We confirm the main features of the spectrum obtained by the plane wave method, namely that for a sufficiently high dielectric contrast a full gap opens in the spectrum be...
متن کاملHopf bifurcations on cubic lattices
Group theoretic means are employed to analyse the Hopf bifurcation on pattern forming systems with the periodicity of the face-centred (FCC) and bodycentred (BCC) cubic lattices. We find all C-axial subgroups of the normal form symmetry group by first extending the symmetry to a larger group. There are 15 such solutions for the FCC lattice, of which at least 12 can be stable for appropriate par...
متن کاملShort-range ordering in face-centered-cubic Ni3AI
Ftis of fee NilAl with suppressed short-range order (SRO) were prepared by physical vapor deposition of N&Al onto room-temperature substrates. Extended electron energy-loss fine-structure spectra were obtained from both Al K and Ni h3 edges. After the samples were annealed for various times at 150 “C!, a moderate growth of SRO was observed in the first-nearest-neighbor environments of both the ...
