Abstract
The objective of the paper is to investigate the radar absorption of honeycombs and foldcores with printed conductive patterns. These structures can be manufactured by first printing conductive Frequency Selective Surfaces (FSS) on planar substrates, which then can be used to shape [...]Abstract
This work analyzes structural waves that propagate freely along taut cables, characterized by a discrete array of scatter elements. The outcomes underline the role played by the periodic distribution of such elements, whose presence alters the response of the system when subjected [...]

An adaptive method for designing the infill pattern of 3D printed objects is proposed. In particular, new unit cells for metamaterials are designed in order to match prescribed mechanical specifications. To this aim, we resort to topology optimization at the microscale driven by an [...]Abstract
This work addresses the analysis of mechanical metamaterials exhibiting, as a distinguishing feature, snap-through instabilities in the elastic regime. Among the various opportunities offered by this feature is the manipulation of the material deformation energy [1] that allows the [...]
