Abstract :
The spectrum of the sources used with the FDTD method is in general unbounded. This means that an amount of energy may be coupled to the grid at frequencies higher than the cutoff frequency. This question has retained little attention in the literature, despite its potential impact on the accuracy of FDTD calculations. It is addressed with details in this presentation.
