Flapping Wing Micro Air Vehicle

, 2018
Background:   Vibrational stability is a natural phenomenon where a system if vibrating at sufficiently high frequencies, can bring itself back into a stable state if perturbed. This is akin to the high frequency flapping that hummingbirds and insects employ to maintain a hovering position and fly. Micro Air Vehicles (MAV) are a subset of air

MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band

Advanced Materials Technologies, EarlyView.
An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...
