This paper presents a class of boundary integral equation methods for the numerical solution of acoustic and electromagnetic time-domain scattering problems in the presence of unbounded penetrable ...

Convolution Quadrature: A numerical technique that discretises convolution integrals by utilising the Laplace transform, thus permitting stable and accurate time-stepping in wave propagation problems.

In a lecture example, we used the convolution integral approach to study the response of an undamped oscillator excited by the rectangular pulse shown below. Here we will apply the graphical ...
