Ray-tracing and Interferometry in Schwarzschild Geometry
Here, we investigate the possible optical anisotropy of vacuum due to gravitational field. In doing this, we provide sufficient evidence from direct coordinate integration of the null-geodesic equations obtained from the Lagrangian method, as well as ray-tracing equations obtained from the Plebanski’s equivalent medium theory. All calculations are done for the Schwarzschild geometry, which resu...
متن کاملCalculation of material properties and ray tracing in transformation media.
Complex and interesting electromagnetic behavior can be found in spaces with non-flat topology. When considering the properties of an electromagnetic medium under an arbitrary coordinate transformation an alternative interpretation presents itself. The transformed material property tensors may be interpreted as a different set of material properties in a flat, Cartesian space. We describe the c...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولPower Absorption Calculation for Electron Cyclotron Resonance Heating in H-1 Heliac
Power absorption is calculated for electron cyclotron resonance heating (ECRH) in the H-1 heliac device by using a ray tracing numerical code. The three-dimensional magnetic field structure and the bean shape of flux surfaces are considered. The calculation results show that the second harmonic extraordinary mode heating is effective even at low density if the launching direction is properly ad...
متن کاملEffect of Magnetic Field Ripple on ECCD in Heliotron J
Electron cyclotron current drive (ECCD) experiment has been made in the helical-heliotron device, Heliotron J. A wide configuration scan shows that the EC driven current is strongly dependent on the magnetic ripple structure where the EC power is deposited. As the EC power is deposited on the deeper ripple bottom, the EC driven current flowing in the Fisch-Boozer direction decreases, and the re...
