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 group continued well into the 1990s and toured with a five-piece band including Leona Carter on keys. The 1984 John Hughes' teen film "Sixteen Candles" took its title from The Crests' song, which was re-recorded by The Stray Cats for the"Sixteen Candles" soundtrack. In June 1987, for a concert in Peekskill, New York, Maestro, Carter, Torres, and Gough (The Original Crests) reunited as "The Crests", which was organized by Carter. From 1990-2010, Johnny Maestro invited Carter to join him and The Brooklyn Bridge to record with them and to re-record some of their greatest hits. From the late 2000s until
