Liu, Feng | Self-consistent tight-binding method | A self-consistent tight-binding formalism is described. The self-consistency is achieved by the introduction of a chemical hardness matrix and a generalization of the Huckel model to make the tight-binding Hamiltonian an implicit functional of the charge density. Studies of the band structures of d... | Tight-binding method; Self-consistency; Huckel model | 1995-10 |

Furse, Cynthia M.; Gandhi, Om P. | Why the DFT is faster than the FFT for FDTD time-to-frequency domain conversions | Although it is a time-domain method, the finite difference time-domain (FDTD) method has been used extensively for calculating frequency domain parameters such as specific absorption rate, radar cross-section, and S-parameters. When a broad frequency band is of interest, using a broad-band pulsed ... | Discrete Fourier transform; DFT; Fast Fourier transform; FFT; Finite-difference time-domain; FDTD; Frequency domain parameters | 1995-10 |
