Three-dimensional vector waves in time-variant materials, with applications in time-reversed focusing and Green's function retrieval
Kees Wapenaar, Dirk-Jan van Manen
The behavior of wave propagation and scattering in time-variant materials has been studied by many authors, for electromagnetic as well as for mechanical waves. Most studies consid…
On the relation between time-reversed acoustics and Green's function retrieval in space-variant and in time-variant materials
Kees Wapenaar, Johannes Aichele, Dirk-Jan van Manen
The methods of time-reversed acoustics and Green's function retrieval are traditionally deployed for classical inhomogeneous, time-invariant materials. The mutual relation between…
Representations for multidimensional down-down deconvolution of ocean-bottom seismic data: theory and practical implications
Kees Wapenaar, Matteo Ravasi, Claudio Bagaini
Multidimensional up-down deconvolution effectively eliminates surface-related multiples from ocean-bottom seismic data. Recently, several down-down deconvolution methods have been…
Reciprocity and representation theorems for rotational seismology
Kees Wapenaar
Recently, there has been an increasing interest in employing rotational motion measurements for seismic source inversion, structural imaging and ambient noise analysis. We derive r…
Multiple reflections on Huygens' principle
Kees Wapenaar
According to Huygens' principle, all points on a wave front act as secondary sources emitting spherical waves, and the envelope of these spherical waves forms a new wave front. In…
Recursive Interferometric Surface-wave Suppression For Improved Reflection Imaging
Faezeh Shirmohammadi, Deyan Draganov, Ranajit Ghose +3
High-resolution seismic reflections are essential for imaging and monitoring applications. In seismic land surveys using sources and receivers at the surface, surface waves often d…

Dirk-Jan van Manen, Johannes Aichele, Jonas Müller +2
We derive time reflection and transmission coefficients for 1D acoustic waves encountering a time boundary at which the properties of the medium change instantaneously. The time re…

Kees Wapenaar
The study of wave propagation and scattering in time-dependent materials is a rapidly growing field of research. Whereas for 1D applications there is a simple relation between the…
Waves in space-dependent and time-dependent materials: a systematic comparison
Kees Wapenaar, Johannes Aichele, Dirk-Jan van Manen
Waves in space-dependent and time-dependent materials obey similar wave equations, with interchanged time- and space-coordinates. However, since the causality conditions are the sa…
Application of virtual seismology to DAS data in Groningen

The Marchenko algorithm can suppress the disturbing effects of internal multiples that are present in seismic reflection data. To achieve this, a set of coupled equations with four…
Target-oriented least-squares reverse-time migration with Marchenko redatuming and double-focusing: Field data application
Aydin Shoja, Joost van der Neut, Kees Wapenaar
Recently, the focus of reflection seismologists has shifted to applications where a high-resolution image of the subsurface is required. Least-Squares Reverse-Time Migration (LSRTM…
The role of the background velocity model for the Marchenko focusing of reflected and refracted waves
Mert Sinan Recep Kiraz, Roel Snieder, Kees Wapenaar
