Abstract :
In this contribution, we consider a limited-view inverse scattering from thin, arc-like electromagnetic inclusions. For this purpose, a non-iterative algorithm operating at multiple time-harmonic frequencies is used to find such points of inclusion and generate a good initial guess. With this guess, a level set strategy is applied to retrieve the complete shape of the unknown thin inclusion. The approaches proposed here are in line with recent investigations as described in [5], [7]. Numerical simulations will exhibit that this algorithm performs satisfactorily even with the presence of a moderate quantity of random noise on the data.
