Strain-Dependent Birefringence Of Elastic Polymers
The optical parameters (refractive index, absorption coefficient) of opaque dielectric materials can be measured with terahertz (THz) Time-Domain spectroscopy (TDS). By using a THz beam of known polarization and measuring both components of the transmitted THz field, it is possible to determine the birefringence present in an anisotropic material. In this work we used polarization sensitive (PS...

در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
15 صفحه اولimproved laser induced birefringence in highly doped optical polymers
application of polymers in novel and advanced scientific technologies is increasingly expanding. in this regard, optical polymers among different materials have found a special and unique position. a novel dye doped polymer thin film was prepared by taking advantage of dye molecules' interaction with the host environment. this sample, like self-assembled structures, makes use of this inter...
متن کاملBirefringence Properties and Surface Relief Grating Formation on Methylacrylate Polymers with Photochromic Side Chains
We have studied light-induced birefringence (LIB) and surface relief grating (SRG) formation in the series of methylacrylate polymers. The effect of material structure such as length of photochromic side chain, glass transition temperature and molecular structure of azo units on LIB and SRG are studied. The optical formation of self-induced SRG on films of these materials is also presented.
متن کاملInvestigation of Thermal Dispersion and Thermally-Induced Birefringence on High-Power Double Clad Yb:Glass Fiber Laser
In this work the effects of heat generation on the modes of Yb:Glass double clad fiber laser were investigated. The thermal dispersion and thermally-induced birefringence were considered when the gain medium becomes an anisotropic medium. The results showed considerable modifications of laser modes profiles, in particular for transfer magnetic (TM) and transfer electric (TE) modes which their p...
