Ageing infrastructure and the move towards more advanced materials raises new, currently unsolved, inspection challenges. Fatigue and creep damage are two of the most common modes of failure in ...
Abstract: This paper proposes a retrodirective array based on dielectric resonator antennas (DRAs). Through the dual-mode resonance of the antenna, the rectangular DRA element achieves a broadband ...
Abstract: In this paper, we propose a novel phased array with movable antennas (PAMA). By replacing traditional phase shifters with movable antennas, PAMA eliminates insertion loss of phase shifters ...
