This work addresses the numerical solution of time-domain boundary integral equations arising from acoustic and electromagnetic scattering in three dimensions. The semidiscretization of the time-domain boundary integral equations by Runge-Kutta convolution quadrature leads to a lower triangular Toeplitz system of size N. This system can be solved(More)
In this paper we present a modified convolution quadrature (CQ) algorithm for the discretization of time-domain boundary integral equations as used for acoustic or electromagnetic scattering. Standard, low-order CQ schemes are strongly dissipative, especially for waves with energies at high frequencies. High-order, Runge-Kutta based schemes are much less(More)
