The early detection of failures in structures is a subject of great interest in engineering; several of these techniques are linked with the elastic wave propagation, using guided waves is one of ...

JCPS Superintendent Dr. Brian Yearwood is suggesting major cuts to the district’s central office, which consists of employees who don’t report to work at a specific school. The trial began in the case ...

Abstract: This article introduces a radial rectangular concentric grating (RRCG) backward wave oscillator (BWO). The design utilizes a radial sheet electron beam (RSEB). It aims to overcome the ...

k-Wave is an open source MATLAB toolbox designed for the time-domain simulation of propagating acoustic waves in 1D, 2D, or 3D [1]. The toolbox has a wide range of functionality, but at its heart is ...

Abstract: In this paper, an all-metal millimeter-wave (mm-Wave) flltenna using double-grating rectangular waveguide (DGRWG) and spoof surface plasmon polaritons (SSPPs) is proposed. The DG-RWG ...

Modern satellites rely on electromagnetic waveguides—hollow structures that carry high-power signals between components such ...
