Microwave Scattering Characteristics of a Cylindrical Conductor Coated by Dispersive Metamaterials with an Intervening Air Gap

open access: yesAdvanced Electromagnetics, 2022
Plane wave scattering characteristics of a conducting cylinder coated by a layer of metamaterial (MTM) having dispersive and lossy constitutive parameters – permittivity (ε) and permeability (μ) - with an intervening air gap is investigated by using the ...

Improvement in seismic performance of building with BRBs [PDF]

open access: yesЖурнал інженерних наук, 2021
Buckling restrained braces (BRBs) are a somewhat ongoing improvement in the field of seismic-safe steel structures. Their unmistakable component is the non-clasping conduct regularly accomplished by encasing a steel center in a substantially filled ...

Effect of heat transfer on peristaltic flow of Newtonian fluid through eccentric cylinders

open access: yesCase Studies in Thermal Engineering, 2023
Heat transfer effect on peristaltic Newtonian flow in an annular region of eccentric cylinders is considered. An approximate solution for temperature and velocity is obtained using perturbation technique. For constant flow rate, the variation of pressure
