Electromagnetic 3D subsurface imaging with source sparsity for a synthetic object
Sampsa Pursiainen, Mikko Kaasalainen
This paper concerns electromagnetic 3D subsurface imaging in connection with sparsity of signal sources. We explored an imaging approach that can be implemented in situations that…
Orbiter-to-orbiter tomography: a potential approach for small planetary objects
Sampsa Pursiainen, Mikko Kaasalainen
The goal of this paper is to advance mathematical and computational methodology for orbiter-to-orbiter radio tomography of small planetary objects. In this study, an advanced full…
Advanced boundary electrode modeling for tES and parallel tES/EEG
Britte Agsten, Sven Wagner, Sampsa Pursiainen +1
This paper explores advanced electrode modeling in the context of separate and parallel transcranial electrical stimulation (tES) and electroencephalography (EEG) measurements. We…
Electroencephalography (EEG) Forward Modeling via H(div) Finite Element Sources with Focal Interpolation
Sampsa Pursiainen, Johannes Vorwerk, Carsten H. Wolters
The goal of this study is to develop focal, accurate and robust finite element method (FEM) based approaches which can predict the electric potential on the surface of the computat…
A Mixed Finite Element Method to Solve the EEG Forward Problem
Johannes Vorwerk, Christian Engwer, Sampsa Pursiainen +1
Finite element methods have been shown to achieve high accuracies in numerically solving the EEG forward problem and they enable the realistic modeling of complex geometries and im…
