Autonomous Unmanned Underwater Vehicles Development Tendencies
Procedia Engineering, 2015 AbstractThis article gives a brief overview of the AUV development history from the beginning to the present day. We have considered different types of AUV from remote operated vehicles (ROV) to biomimetic AUV. Our goal is to define the vector of AUV development at an early date on the basis of the AUV history.

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 ...
