  Energy self sufficiency, as well as optimal management of power in buildings
is gaining importance, while obtaining power from traditional fossil energy
sources is becoming more and more expensive. In this context, millimeter scale
metasurfaces can be employed to harvest energy from microwave sources. They can
also be used as sensors in the microwave regime for efficient power management
solutions. In the current study, a simple spray printing method is proposed to
develop metasurfaces in construction materials, i.e., plasterboard and wood.
Such materials are used in the interior design of buildings; therefore, the
implementation of metasurfaces in large areas, such as walls, doors and floors,
is realized. The fabricated metasurfaces were characterized regarding their
electromagnetic performance. It is hereby shown that the investigated
metasurfaces exhibit an efficient electromagnetic response in the frequency
range 4 to 7 GHz, depending on the MS. Thus, spray printed metasurfaces
integrated on construction materials can potentially be used for
electromagnetic applications, for buildings power self efficiency and
management.
