We present a variational approach to the inverse problem of electromagnetic imaging of determining the coefficients μr and r in the Maxwell system, from near field data, measured on the boundary of a… Expand

We consider the system of second order elliptic equations -Σk∇ (Ei,k ∇uk)+ Pi,kuk=0, 1 ≤ i ≤ n in a bounded simply-connected domain B. Using a factorisation method ansatz, we show that the difference… Expand

In this work we present a variational algorithm to determine the parameters iir(x) and er(x) in the Maxwell system VxE + k xTH = 0, V x H - kerE = 0 in a body Q from boundary measurements of… Expand

We consider the solvability of the semilinear parabolic differential equation \[\frac{\partial u}{\partial t}(x,t)- \Delta u(x,t) + c(x,t)u(x,t) = \mathcal{P}(u) + \gamma (x,t)\] in a cylinder… Expand
