Generalised eigenfunction expansion and singularity expansion methods for two-dimensional acoustic time-domain wave scattering problems
Ben Wilks, Michael H. Meylan, Fabien Montiel +1
Time-domain wave scattering in an unbounded two-dimensional acoustic medium by sound-hard scatterers is considered. Two canonical geometries, namely a split-ring resonator (SRR) an…

Generalised eigenfunction expansion and singularity expansion methods for canonical time-domain wave scattering problems
Ben Wilks, Michael H. Meylan, Fabien Montiel +1
The generalised eigenfunction expansion method (GEM) and the singularity expansion method (SEM) are applied to solve the canonical problem of wave scattering on an infinite stretch…
