Abstract The digital and programmable metasurfaces, as opposed to conventional offer a more sophisticated method of collaborating information physics, showcasing several real-time controls electromagnetic (EM) ways in succinct ways. In this work, we propose multi-frequency amplitude-programmable (MFAP) metasurface with multiple frequency channels enhance the presentation manipulation EM data. W...

The present article investigates effects of the multi-frequency excitation on the output power of a piezomagnetoelastic energy harvester. The piezomagnetoelastic power generator is assumed to operate in the mono-stable mode. A perturbation technique based on the method of multiple scales is employed to develop an analytical solution to nonlinear differential equations governing the system dynam...

Wireless networking is rapidly growing and becomes an inexpensive technology which allows multiple users to simultaneously access the network and the internet while roaming about the campus. In the present work , the software development of a wireless LAN(WLAN) is highlighted. This WLAN utilizes direct sequence spread spectrum (DSSS) technology at 902MHz RF carrier frequency in its physical lay...

in this paper, a novel compensator based on magnetically controlled reactor with fixed capacitor banks (fc-mcr) is introduced and then power system stability in presence of this compensator is studied using an intelligent control method. the problem of robust fc-mcr-based damping controller design is formulated as a multi-objective optimization problem. the multi-objective problem is concocted ...

Abstract PPP-RTK which takes full advantages of both Real-Time Kinematic (RTK) and Precise Point Positioning (PPP), is able to provide centimeter-level positioning accuracy with rapid integer Ambiguity Resolution (AR). In recent years, the development BeiDou Navigation Satellite System (BDS) Galileo navigation satellite system (Galileo) as well modernization Global (GPS) GLObal NAvigation (GLON...
