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

We consider a linearised inverse conductivity problem for electromagnetic waves in three dimensional bounded domain at high time-harmonic frequency. Increasing stability bounds the coefficient full Maxwell system and simplified transverse electric mode are derived. These contain Lipschitz term with factor growing polynomially terms of frequency, Holder term, logarithmic which decays respect to frequency as power. To validate this increasing numerically, we propose reconstruction algorithm aiming recovery sufficiently many Fourier modes conductivity. A numerical evidence sheds light on influence confirms improved resolution higher frequencies.
