Optical Cloak of Invisibility
We present the design and analysis of an optical cloak of invisibility with non-magnetic metamaterials. The general recipe for the implementation of such a device is provided. The cloaking performance is illustrated with finite-element simulations. ©2007 Optical Society of America OCIS codes: (230.3990) Microstructure devices; (160.4760) Optical properties; (999.9999) Meta-materials

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Making the DDA Run: Two-Dimensional Ray Traversal Using Runs and Runs of Runs
Iterative algorithms based on runs and runs of runs are presented to calculate the cells of the two–dimensional lattice intersected by a line of real slope and intercept. The technique is applied to the problem of traversing a ray through a two–dimensional grid. Using runs or runs of runs provides a significant improvement in the efficiency of ray traversal for all but very short path lengths w...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
