 | Furse, Cynthia M. | Faster than fourier: ultra-efficient time-to-frequency-domain conversions for FDTD simulations | This tutorial compares several methods of converting from the time to the frequency domain for FDTD simulations. Applications include calculations of field or power distributions, antenna impedance, and radiation patterns. The traditional Fourier transform methods are compared to two methods based o... | FDTD simulations; FDTD methods; Finite-difference time-domain; Computation time; Frequency domain analysis; Time domain analysis; Discrete Fourier transform | 2000-01-01 |

 | 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 |
