Field intensity shaping is a challenging open problem of interest for many applications. The several approaches proposed are based on a complete knowledge of both the scenario and the target. This, instead, is not necessarily possible. The aim of this communication is to propose a novel adaptive procedure able to shape the field intensity in an unknown (or partially unknown) scenario. The approach originates from the physical interpretation of the Linear Sampling Method and takes advantage from using both control points and an additional degree of freedom represented by phase shifts of the field at these control points.
