Field-only integral equation method for time domain scattering of electromagnetic pulses

open access: yes, 2018
The scattering of electromagnetic pulses is described using a non-singular boundary integral method to solve directly for the field components in the frequency domain, and Fourier transform is then used to obtain the complete space-time behavior.
