On the Settling Speed of Dilute Arrays of Spheres [PDF]
, 1974 A method is developed to calculate the settling speed of dilute arrays of spheres for the three cases of: I, a random array of freely moving particles; II, a random array of rigidly held particles; and III, a cubic array of particles.

Fast Hydrogel Micro‐Actuators Driven by Electric Fields
Advanced Materials, EarlyView.We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...

An investigation of a frequency diverse array [PDF]
, 2009 This thesis presents a novel concept for focusing an antenna beam pattern as a function of range, time, and angle. In conventional phased arrays, beam steering is achieved by applying a linear phase progression across the aperture.

Cylindrical Resonator Sectorally Filled With DNG Metamaterial and Excited by a Line Source [PDF]
, 2012 A circular cylindrical resonator with metallic walls is analyzed in the phasor domain. The resonator contains a wedge of double-negative (DNG) metamaterial that is anti-isorefractive to the double-positive (DPS) material filling the remaining volume of ...

An Efficient 2-D DOA Estimation for a Cylindrical Conformal Array with Unknown Mutual Coupling
International Journal of Antennas and Propagation, 2018 The limited space of a conformal array may lead to a serious mutual coupling effect, which will significantly affect the performance of direction of arrival (DOA) estimation algorithms.
