A linearised inverse conductivity problem for the Maxwell system at a high frequency

Victor Isakov, Shuai Lu, Boxi Xu

We consider a linearised inverse conductivity problem for electromagnetic waves in a three dimensional bounded domain at a high time-harmonic frequency. Increasing stability bounds…
