Array of Arrays: Optimizing Phased Array Tiles

IEEE Antennas and Wireless Propagation Letters, 2021
This letter discusses some of the challenges for realizing large millimeter-wave phased array antennas using multiple scalable arrays (tiles). The letter uses the radiation pattern multiplication and the array of arrays concepts to analyze the effect of the tiling gap on the large array radiation pattern.

Reverse Phase Protein Arrays

2020
Reverse phase protein arrays (RPPA) are used to quantify proteins and protein posttranslational modifications in cellular lysates and body fluids. RPPA technology is suitable for biomarker discovery, protein pathway profiling, functional phenotype analysis, and drug discovery mechanism of action.

Optical phased-array ladar

Applied Optics, 2014
We demonstrate a ladar with 0.5 m class range resolution obtained by integrating a continuous-wave optical phased-array transmitter with a Geiger-mode avalanche photodiode receiver array. In contrast with conventional ladar systems, an array of continuous-wave sources is used to effectively pulse illuminate a target by electro-optically steering far ...

The NMR phased array

Magnetic Resonance in Medicine, 1990
Abstract We describe methods for simultaneously acquiring and subsequently combining data from a multitude of closely positioned NMR receiving coils. The approach is conceptually similar to phased array radar and ultrasound and hence we call our techniques the “NMR phased array.” The NMR phased array offers the signal‐to‐noise ratio ...

Three‐Phase Barker Arrays

Journal of Combinatorial Designs, 2013
AbstractA 3‐phase Barker array is a matrix of third roots of unity for which all out‐of‐phase aperiodic autocorrelations have magnitude 0 or 1. The only known truly two‐dimensional 3‐phase Barker arrays have size 2 × 2 or 3 × 3. We use a mixture of combinatorial arguments and algebraic number theory to establish severe restrictions on the size of a 3 ...

Protein Arrays III: Reverse-Phase Protein Arrays

2017
The reverse-phase protein array (RPPA) is to use highly specific antibodies to interrogate pan or posttranslationally modified protein targets, such as phosphorylated proteins, particularly the proteins involved in cell signaling pathways. In this protocol we will cover the preparation of cell (or tissue) lysates, sample printing, antibody validation ...
