FFT-based simulation using a reduced set of frequencies adapted to the underlying microstructure [PDF]
Computer Methods in Materials Science, 2021 Instead of the classical finite element (FE) based microstructure simulation, a Fast Fourier transform (FFT) based microstructure simulation, introduced by Moulinec and Suquet (1994, 1998), also enables the computation of highly resolved microstructural ...

The Constant Multiplier FFT [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2021 In this paper, we present a new fast Fourier transform (FFT) hardware architecture called constant multiplier (CM) FFT. Whereas rotators in previous architectures must rotate among several different angles, the CM FFT exploits the use of constant multipliers to calculate the rotations.
