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 |
