The adaptive cross approximation algorithm applied to a volumetric method-of-moments for electromagnetic analysis of inhomogeneous bodies

In this communication, the V-MoM formulation is briefly described, together with a strategy to reduce the computational cost using the Adaptive Cross Approximation algorithm (ACA) [3] and an iterative solver based on the Conjugate Gradient (CG), CGACA. Finally, a practical application is presented where the field distribution inside a human body model is calculated.
