Negative Perceptions In The Media

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...

Negative refraction in indefinite media

Initial experiments on wedge samples composed of isotropic metamaterials with simultaneously negative permittivity and permeability have indicated that electromagnetic radiation can be negatively refracted. In more recently reported experiments [Phys. Rev. Lett. 90, 1074011 (2003)], indefinite metamaterial samples, for which the permittivity and permeability tensors are negative along only cert...

Negative index media in microwave waveguide

Microwave waveguide measurements of negative index media (NIM) are reported. Accurate determination of the frequency variation of the complex scattering parameters yields the refractive index " ' ) ( ~ in n n + = ω for the NIM with ' n varying between -3.9 to -0.3 in the passband region of 9.7-10.5 GHz. The results show that transmission is optimized for 1 ' − ≈ n and small " n . PACS numbers: ...
