Linear antenna arrays with bidirectional phase center motion

IEEE Transactions on Antennas and Propagation, 2005
The theoretical and experimental studies of linear antenna arrays with bidirectional phase center motion (BPCM) is presented. BPCM is achieved by exciting only part of the linear array elements and sweeping the excited part from one end to the other and back. The sidelobes of the linear arrays with BPCM experience both upper and lower Doppler frequency

A linear piezoelectric actuator with high flexibility flexible mechanism designed by the bidirectional parasitic motion principle

Review of Scientific Instruments, 2020
This paper proposes a piezoelectric actuator based on the parasitic motion principle which overcomes the disadvantage that piezoelectric actuators designed by the parasitic motion principle always sacrifice reverse directional performance for improving forward directional performance.

On the Viscous Bidirectional Vortex. Part 1: Linear Beltramian Motion

46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010
In this article, a viscous approximation is obtained for the linear, inviscid, Beltramian motion that may be engendered in a confined, bidirectional vortex chamber. Using the theory of matched-asymptotic expansions, viscous corrections are developed near the core region, where a forced vortex prevails, and near the cylindrical wall, where the no-slip ...
