Abstract: This paper describes a very simple beam steering system which can steer the axial beam of any arbitrarily-large circular array in 2 dimensions, using 3 hybrids and 3 or 4 variable phase ...

Given an array of integers arr[] in a circular fashion, return the maximum sum of a subarray that can be obtained assuming the array is circular. Note: The solution should account for both regular and ...

Abstract: The rotating phase of orbital angular momentum (OAM) waves can bring new degrees of freedom in the wireless communication and microwave imaging realms, and more generally for inverse ...
