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…
A mechanistic evaluation of the local Bloch wave approximation in graded arrays of vertical barriers
Ben Wilks, Fabien Montiel, Sarah Wakes
Wave interaction with graded metamaterials exhibits the phenomenon of rainbow reflection, in which broadband wave signals slow down and separate into their frequency components bef…
