We present a method to create an internal numerical absorbing boundary within elastic solid
media whose properties are largely unknown and use it to create the first wavefield …

We describe an elastic wave propagation laboratory that enables a solid object to be
artificially immersed within an extended (numerical) environment such that a physical wave …

Seismic advance detection is a method for detecting complex geological formations in a
tunnel face, which is crucial for the safe construction of tunnel projects. During the process of …

Accurately injecting and extrapolating multicomponent seismic data is a major step in elastic
reverse time migration (RTM) and full-waveform inversion. The theoretical basis of this …

We experimentally implement a one-directional virtual geometric periodicity in an elastic
metamaterial. First, unwanted boundary reflections at the domain ends are cancelled …

Many modelling studies of wave scattering require repeated numerical simulations through
models with properties that differ only in a small sub-domain. Hence, it is of interest to …
