Multiple feed reflector antenna analysis
… pattern of a reflector illuminated by a feed array is developed. Geometrical optics is used to determine the incident field via a coordinate transformation approach. The incident field from each element is superimposed to form the total field used in finding the surface currents of the …

Beamforming Techniques and Interference Mitigation Using a Multiple Feed Array for Radio Astronomy
… can be mitigated using a phased array feed in conjunction with a large reflector. A phased array feed would allow radio astronomers to observe fainter signals than is currently possible, while at the same time enabling rapid sky surveys. A phased array feed was designed and simulated, …

Hippocampal microcircuits for social memory specification
… (social recognition) but also between multiple familiar individuals (social specification). Recent studies have implicated hippocampal sub-region dorsal CA2 (dCA2) in social recognition and identified social recognition memory engram in downstream ventral CA1 (vCA1). However, the …

Instigating buoyancy driven convection to improve membrane distillation performance
… and concentration polarization both increase the feed density near the membrane. In this exploratory study, we explore whether these differences in local feed density can instigate buoyancy driven convection in the feed flow and mitigate polarization. We also explore whether we can strengthen this …

Analyzing modal decomposition data of finite antenna arrays
… and therefore are independent of the array feeding method. Whereas CM is often used in the study of single port, electrically small structures that are dominated by one or two modes, our template arrays are electrically large and made of multiple disjoint elements, with multiple feed points. …

Controlling trace impurities in a dividing wall distillation column
… wall distillation columns (DWCs) separate a feed mixture into three pure product streams using one column shell. Though attractive due to capital and operational savings, DWCs have yet to gain widespread industrial acceptance. One notable concern is controllability. The research within this …

Analysis of a Helix Antenna Using a Moment Method Approach With Curved Basis and Testing Functions
… a delta gap source model is used. Straight feed wires may also be added to the helix, and are modeled similarly to the helix by the Method of Moments with triangular basis and pulse testing functions. The primary validation of the curved wire approach is through a comparison with MININEC and …
