On the Exploitation of Non-Radiating Currents for the Design of EM Skins

The constrained design of static passive Electromagnetic Skins (EMS) is addressed within the Smart Electromagnetic Environment (SEME) framework. A synthesis approach employing non-radiating (NR) currents is illustrated to enable the decoupling of (i) the wireless coverage requirements and (ii) the manufacturing and installation constraints. Subsequently, the two objectives can be attained separately in a fast and effective way. In order to validate the proposed NR synthesis method, the constrained design of a multi-beam EMS is presented.
