the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Whistler-mode Propagation in the Collisional Ionosphere of Venus
Waves identified as whistler-mode waves have been observed in the nightside ionosphere of Venus by the Pioneer Venus Orbiter. These waves are propagating in a collisional, weakly magnetized ionosphere, and it has been argued that as such they should be damped through collisions, and the wave should not retain the characteristics of the whistler-mode because of non-linear modifications to the di...
متن کاملRadio-Wave Propagation and Electromagnetic Surface Waves.
1. A Discrepancy and Its Resolution.-The problem of the propagation of radio-waves along the surface of the (plane) earth was first treated in a celebrated paper by A. Sommerfeld (1909).1 Let the (r, (p)-plane of a cylindric system of coordinates coincide with the plane of the earth surface and let the z-axis point vertically upward. Sommerfeld considered a vertically oscillating dipole (radio-...
متن کاملOf the Venus Ionosphere
• A two-dimensional, time-dependent, shock capturing single-sp•ies (O +)hydrodynamic odel of the Venus ionosphere, which solves the coupled continuity, momentum and energy _,•ons for the altitude range of 150 500 km and the solar zenith angle range of 0O 180 ø has been developed and is presented in this paper. It was again demonstrated thathe introduction of topside heat inflows leads to calcul...
متن کاملRecent Advances in FDTD Modeling of Electromagnetic Wave Propagation in the Ionosphere
─ Finite-Difference Time-Domain (FDTD) modeling of electromagnetic wave propagation in the Earth-ionosphere waveguide has gained significant interest over the past two decades. Initially, FDTD modeling capabilities were largely limited to two-dimensional models assuming a plasma ionosphere (but incapable of accounting for Faraday rotation), or to threedimensional global models assuming a simple...
