Abstract: Abstract In this chapter, we compare the performance of two recently proposed hybrid methods for numerically solving the wave equation in two spatial dimensions. The convolution quadrature (CQ) method is employed for the time discretisation, which can be used to transform the original time-domain problem into a system of frequency domain Helmholtz problems with complex wavenumbers.
