The LOREN project was focused on the design and implementation of a technological demonstrator aimed to reduce the radar signature of mobile units by exploiting innovative metamaterials realized with periodic resistive surfaces. These radar absorbing materials have been specifically designed to be integrated in the most critical parts of the mobile unit in terms of backscattered fields, such as antennas and corners. The successful implementation and realization of resistive materials, achieved by using processes and technologies available in the national industry, was one of the most challenging task accomplished. Guidelines for the design of future units have been provided on the basis of the gained physical insight, which has also to take into account the feasibility, cost-efficiency and required form factor of the designed materials.
