Abstract: Vortex electromagnetic waves carrying orbital angular momentum have been widely studied in many fields because of their unique helical phase structure. The vortex electromagnetic waves can ...

This repository contains code examples and explanations for working with arrays in JavaScript. Created as part of an assignment during my learning journey, this project demonstrates various array ...

If you get the You can’t change part of an array error in Microsoft Excel, this post will help you fix the error. An array is essentially a collection of items ...

Abstract: This paper proposes a circularly polarized beamforming technique on volumetric random arrays with each antenna aligned deliberately. This technique seeks to advance the capabilities of ...

ABSTRACT: In high frequency surface wave radar (HFSWR) applications, range and azimuth resolutions are usually lim-ited by the bandwidth of waveforms and the physical dimension of the radar aperture, ...

This paper proposes a three-dimensional (3-D) amplitude tapering technique on volumetric random arrays to minimize array sidelobes and emulate phased array operations on mobile platforms. Our ultimate ...
