The Effect of Steady Flow on the Physical Quantities of Slow mMagneto Acoustic Waves in Solar Coronal Plasma
Published 2020-04-01“…Since the launch of solar space telescopes, many observational evidences for the occurrence of slow MHD waves have been detected in various structures of the solar corona.}In this paper, the effect of steady flow of coronal plasma textbf{on the damping time and other physical quantities} of slow magneto-acoustic waves in the presence of thermal conduction and compressive viscosity is studied.The perturbed and linearized MHD Equations of a flowing coronal plasma are solved both analytically and numerically by Mac Cormack method to investigate the effect of steady flows on physical quantities of slow magneto-acoustic waves.The results of this study show that with increasing magnitude values of the Mach number from 0 to 0.6 and increasing the compressive viscosity and thermal conduction coefficient with increasing the temperature from 2 to 6 MK, the oscillation periods, the damping times and the damping qualities change significantly. …”

Performance Evaluation of Dual-Drive Mach-Zehnder Modulator and Optomechanical Crystal Cavity Comb Generation for All-Optical Band Conversion in 5G-Advanced Cellular Systems
Published 2025-01-01“…Their effectiveness in all-optical frequency conversion depends on their stability in terms of frequency drift, phase noise, and power distribution across the comb lines. This paper evaluates experimentally the generation of optical frequency combs employing two distinct technologies: a dual-driven Mach-Zehnder modulator (DD-MZM) and an optomechanical crystal cavity (OMCC), and experimentally compares their performance for all-optical frequency conversion of 5G data streams. …”
