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
A Wave, a WAC and a Marine no idea what I wanted to do. But he put up the money and we decided on the crazy story "A Wave, a WAC and a Marine"." Karlson called the movie "probably the worst picture ever made... It was a nothing picture, but I was lucky because it was for Monogram and they didn't understand how bad it was because they had never made anything that was any good." However it did launch Karlson's directing career. A Wave, a WAC and a Marine A WAVE, a WAC and a Marine is an American 1944 musical comedy film directed by Phil
