Bloch wave – MoM method the wave numbers in any of the 3 periodic coordinate directions. This can happen for example when the free space wavelength exactly equals the lattice spacing. This is a statistically rare occurrence in computational practice and corresponds to a propagation anomaly similar to a Wood's reflection anomaly for gratings. To compute bands of the crystal (i.e. "k"-"k" diagrams), successive values of frequency ("k") are tried - in conjunction with pre-selected values of propagation constant ("k") and propagation direction (θ & φ) - until a combination is found which drives the determinant of the matrix to zero. Equation (4.2) has been
The Crests No: 160201) Unreleased recordings The Crests The Crests were an American doo-wop group, formed by bass vocalist J.T. Carter in the mid 1950s. The group had several Top 40 hits in the late 1950s and early 1960s on Coed Records. Their most popular song, "16 Candles", rose to #2 on the "Billboard" Hot 100 chart in February 1959 selling over one million copies and earning a gold disc status. The group's other hits include "Step By Step", "The Angels Listened In", "Trouble In Paradise", "Six Nights A Week", and "A Year Ago Tonight". The Crests were the first interracially mixed
