In this paper, a three-layer dielectric structure is presented as innovative unit-cell element for transmitarray (TA) antennas with enhanced bandwidth. It consists of central layer, varying size square hole, used to compensate the phase incident field and located between two other identical layers linearly tapered holes, acting matching circuits. The effectiveness demonstrated by numerical experimental results here presented. As first step, three different TAs increasing are designed...
Abstract Rapid Prototyping (RP) promises to induce a revolutionary impact on how the objects can be produced and used in industrial manufacturing as well everyday life. Over time standard technique 3D Stereolithography (SL) has become fundamental technology for RP Additive Manufacturing (AM), since it enables fabrication of from cost-effective photocurable resin. Efforts obtain devices more complex than just mere aesthetic simulacre, have been spent with uncertain results. The...

Nanocomposite laminates containing carbon fibers, epoxy, and multiwalled nanotubes were fabricated using a vacuum bag process. Ecofriendly ionic liquid (5 wt%)-treated (pristine nickel-coated) added to the epoxy independently, in amounts ranging from 1 wt% 3 wt%, order tailor mechanical, electrical, thermal performance of manufactured fiber composite laminates. These nanocomposite later characterized through flexural testing, dynamic mechanical analysis, impedance spectroscopy, conductivity...
Concerning environmental safety and mitigating the risk of water pollution, electroplating industry, historically reliant on use elevated concentrations heavy metals to achieve high-quality products, faces a crucial challenge in monitoring wastewater enriched with these metals, notorious for their adverse effects ecosystems human health. Chromium, both oxidation states Cr (III) (VI), emerges as prominently employed metal, yielding noteworthy outcomes throughout galvanisation process. This...
MEMS devices are more and commonly used as sensors, actuators, microfluidic in different fields like electronics, opto-electronics, biomedical engineering. Traditional fabrication technologies cannot meet the growing demand for device miniaturisation time reduction, especially when customised required. That is why additive manufacturing increasingly applied to MEMS. In this review, attention focused on Italian scenario regard 3D-printed MEMS, studying techniques materials their fabrication....
Renewable energy-based technologies and increasing IoT (Internet of Things) objects population necessarily require proper energy storage devices to exist.
