Index of Refraction of Magnesium Oxide
In 1935, shortly after moderate sized artificially grown crystals of magnesium oxide became available, two papers were published dealing with the optical properties of this material. 2 Strong and Brice measured the index of refraction of two prisms, cut from the same crystal, by photographic and visual means over the range from 2536 to 7065 A. Barnes, Brattain, and Seitz investigated the transm...

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
15 صفحه اولThe negative index of refraction demystified
We study electromagnetic wave propagation in mediums in which the effective relative permittivity and the effective relative permeability are allowed to take any value in the upper half of the complex plane. A general condition is derived for the phase velocity to be oppositely directed to the power flow. That extends the recently studied case of propagation in mediums for which the relative pe...
متن کاملNegative index of refraction in optical metamaterials.
A double-periodic array of pairs of parallel gold nanorods is shown to have a negative refractive index in the optical range. Such behavior results from the plasmon resonance in the pairs of nanorods for both the electric and the magnetic components of light. The refractive index is retrieved from direct phase and amplitude measurements for transmission and reflection, which are all in excellen...
متن کاملEco-friendly Synthesis of Magnesium Oxide Nanoparticles using Arabic Gum
Magnesium oxide nanoparticles were synthesized using Arabic gum as a biotemplate andmagnesium nitrate as the magnesium source by the sol-gel method. This method has manyadvantages such as nontoxic, economic viability, ease to scale up, less time consuming andenvironmental friendly approach for the synthesis of MgO nanoparticles without using anyorganic chemicals. Nanoparticles were characterize...
