Array of Arrays: Optimizing Phased Array Tiles
IEEE Antennas and Wireless Propagation Letters, 2021This 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.

Array Tomography: Production of Arrays
Cold Spring Harbor Protocols, 2010INTRODUCTIONArray tomography is a volumetric microscopy method based on physical serial sectioning. Ultrathin sections of a plastic-embedded tissue are cut using an ultramicrotome, bonded in an ordered array to a glass coverslip, stained as desired, and imaged.

Array generation with lenslet arrays
Applied Optics, 1991Lenslet arrays can be used as phase gratings, having many diffraction orders with equal intensity. Applications are multiple imaging and illumination of arrays of optical or optoelectronic devices in digital optics. The homogeneity of the intensities within the array can be improved by using field lenslets.

Arrays of parametric receiving arrays
The Journal of the Acoustical Society of America, 1972Theory is presented to describe the response of arrays whose elements consist of parametric end-fire receivers. The results of measurements on arrays containing up to four elements are presented in support of the theory. Electronic steering of this type of array is also addressed.

Science, 1997
With the National Science Foundation about to give the go-ahead for the Millimeter Array and several smaller projects under way, some astronomers fear that there won't be enough money to support research on these new instruments.

Array redundancy for active line arrays
IEEE Transactions on Image Processing, 1996Active imaging arrays are used to image scenes composed of reflectors of transmitted radiation, and in many such applications, line arrays are employed. In this paper, we discuss scanned active line arrays for imaging based on image synthesis. We define the novel concept of array redundancy for active arrays, analogous to the well-known concept of ...

Efficient Evaluation of Array Subscripts of Arrays
IBM Journal of Research and Development, 1972The APL language allows subscripted expressions such as A[I;J;K], where A is an array and I, J and K may be scalars, vectors or arrays of any size and shape. We describe an efficient method of evaluating these expressions. The method is quite general and yet it does recognize all the special cases in which multiple subscripts can be reduced to a ...

Virtually every type of application, program, and component uses arrays for data storage—regardless of the programming language used. While Visual Basic lets you easily create arrays, it contains no intrinsic methods for most common tasks for working with arrays. You need to write your own subroutines (or take advantage of those written by someone else)

Protein Arrays II: Antigen Arrays
2017Antigen arrays are fabricated using various antigens such as DNA, histones, synthetic peptides, recombinant proteins, or cell extracts to detect autoantibodies in autoimmune diseases, alloantibodies in transplantation, drug-induced antibodies or cancer-induced antibodies in blood or cell culture supernatant.
