We examine the nonlinear inverse problem of electromagnetic induction to recover electrical conductivity. As this is an ill-posed roblem based on inaccurate data, there is a critical need to find the reliable features of the models of electrical conductivity. We resent a method for obtaining bounds on Earth’s average conductivity that all conductivity profiles must obey. Our method is based ompletely on optimization theory for an all-at-once approach to inverting frequency-domain… CONTINUE READING
