Time-domain finite-difference (TDFD) method is the most dominant approach for seismic wavefield simulation. Due to the memory and computational cost of the computer, finite-difference (FD) simulations ...

Calculation: A representation of a network of electromagnetic waveguides (left) being used to solve Dirichlet boundary value problems. The coloured diagrams at right represent the normalized ...

The word phase has a clear definition for pure traveling sinusoidal waves. This is not the same for music signals since all equalizers shift phase with frequency. Sinusoidal waveforms of the same ...
