Multiresolution finite element contrast source inversion method

2013 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2013
Electromagnetic inverse scattering problems are relevant to a broad range of applications, including biomedical imaging, subsurface prospecting and security monitoring, only to mention some examples. For such a reason, there is always a huge interest in developing effective inversion methods capable to provide reliable imaging results.

Adaptive finite element methods for nonlinear inverse problems

Proceedings of the 2009 ACM symposium on Applied Computing, 2009
Nonlinear inverse problems are usually formulated as optimization problems on function spaces constrained by partial differential equations. As a consequence, in realistic, three-dimensional cases, they become extraordinarily expensive to solve numerically, and advanced methods like adaptive mesh refinement become indispensible.
