Transparent Smart Electromagnetic Skins for Outdoor to Indoor Communications

In this communication, preliminary results on the design of a passive, transparent, Smart Electromagnetic Skin (SES) for outdoor-to-indoor (O21) communications are presented. Contrary to what is already available in literature, here a dielectric-only configuration is proposed, in order to avoid the presence of metallizations that can reduce the transparency. Moreover, a glass layer is directly introduced in the unit cell, to take into account the presence of the window. Different configurations have been designed and numerically analyzed: the obtained results demonstrate the feasibility of the proposed solution and its effectiveness.
