Abstract
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)
