A sparse linear array, composed of a uniformly spaced core subarray and an extended sparse subarray, is synthesized using a harmony search (HS) and an exploratory harmony search (EHS) algorithms. The ...

A linear array synthesis method using element-level pattern diversity (ELPD) is presented. Compared with conventional array, the ELPD array provides one more degree of freedom in antenna synthesis.

This Backgrounder presents a data-driven analysis of the H-1B visa program, highlighting critical shortcomings. The data reveal that a significant proportion of H-1B workers are paid below the ...
