A Lumped RC Equivalent Circuit of Head Tissues for Dispersive Neuro-Electromagnetic Modeling
Angelo Faccia, Ermanno Citraro, Francesco P. Andriulli
Accurate modeling of electric potential and current distribution in head tissues is crucial for the design and evaluation of neuro-sensing and neuro-stimulation systems operating i…
A Lumped-Element Electrical Model of the Human Head for Brain-Oriented Applications
Angelo Faccia, Ermanno Citraro, Francesco P. Andriulli
In this work, we present a compact surrogate circuit for electro-quasi-static (EQS) head modeling. A three-shell geometry (brain, skull, scalp) is considered, and each layer is mod…
On some Operator Filtering Strategies Based on Suitably Modified Green's Functions
Matteo E. Masciocchi, Ermanno Citraro, Alexandre Dély +3
Recent contributions showed the benefits of operator filtering for both preconditioning and fast solution strategies. While previous contributions leveraged laplacian-based filters…
Stabilized Single Current Inverse Source Formulations Based on Steklov-Poincaré Mappings
Paolo Ricci, Ermanno Citraro, Adrien Merlini +1
The inverse source problem in electromagnetics has proved quite relevant for a large class of applications. In antenna diagnostics in particular, Love solutions are often sought at…
On a Constrained Pseudoinverse for the Electromagnetic Inverse Source Problem
Ermanno Citraro, Alexandre Dély, Adrien Merlini +1
Inverse source approaches have shown their relevance for several applications in the past years. They rely on the solution of an ill-posed problem where near-field/current data is…
