چکیده
This paper presents an EM analysis of dispersions & discontinuities in a microstrip transmission lines. Dispersion characteristics of a microstrip lines are investigated by the existing models for study of microstrip lines and then compare the results with Software Simulation. Dispersions on microstrip lines with characteristics impedance 50Ω are investigated for the frequency range 1 to 18 GHz for Alumina substrate and 1 to 3 GHz for FR4. The frequency dependent characteristics of microstrip dispersions and discontinuities were analyzed by MoM based Sonnet Software Simulation. This paper discusses two issues concerning the dispersions and bend discontinuity for Alumina and FR4. The CAD analyses for compensated and non-compensated discontinuities are simulated & compared. The Sonnet Software is used for the analysis of variations in effective dielectric constant, scattering parameters & current densities at various frequency range. The work is of practical significance for microwave researchers and engineers.

متن کاملExperimental Investigation of Submerged Vanes’ Shape effect on river-bend stability
In river meandering, when flow passes through a bend, reduction of flow velocity and rising hydrostatic pressure cause super elevation phenomena at outer side and reduction of water surface at inner-side of the bend. A helical motion results, causing erosion of the outer side of the bend. Installation of submerged vanes on the stream bed can reduce erosion of the outer bank significantly. In th...

In order to analyze the slope stability in open-pit mines, the structural parameters of rock mass such as persistence and spatial orientation of discontinuities are characterized through field surveys, which involve spending high costs and times as well as posing high risks of rock toppling and rock fall. In the present work, a new application of terrestrial digital photogrammetry is introduced...
