Modeling of an unmanned hybrid aerial vehicle

2014 IEEE Conference on Control Applications (CCA), 2014
In this paper, the mathematical modeling of ahybrid aerial vehicle is presented. This vehicle is a combinationof a fixed-wing aircraft and a multirotor helicopter. Thisvehicle is thus capable of vertical take off and landing (VTOL)and of cruising forward flight.

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

Advanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB
