Abstract: In distributed coherent aperture radar (DCAR), the fundamental problem in ensuring the full coherence of the radar system is how to realize the precise positioning of the subarray. The ...

Abstract: A novel and effective method for the design of maximum directivity irregular phased arrays is proposed in this article. By decomposing the radiation pattern of irregular arrays (IAs) into ...

How did a Georgia Tech team overcome certain limitations to develop an antenna that harvest energy in the 28-GHz band? The key role played by the Rotman lens in making it all happen. Test results ...

Given a non-empty binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child ...

You are given an array (ARR) of length N, consisting of integers. You have to find the sum of the subarray (including empty subarray) having maximum sum among all subarrays. A subarray is a contiguous ...
