Inhomogeneous lens antenna design with fan-beam radiation pattern
《Chinese Optics Letters》2016年第12期89-93,共5页Mohammad Mahdi Taskhiri Mohammad Khalaj-Amirhosseini 
This Letter presents an original technique to design and synthesize an inhomogeneous asymmetrical lens resulting in a special fan-beam radiation pattern in a wide frequency bandwidth. The vertical and horizontal plane...

Vector properties of a tunable random electromagnetic beam in non-Kolmogrov turbulence
《Chinese Optics Letters》2016年第8期1-5,共5页王静 朱时军 李振华 
supported by the National Natural Science Foundation of China (No. 11504172);the Natural Science Foundation of Jiangsu Province (No. BK20150763);the Project Funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions
Analytical formulas for a class of tunable random electromagnetic beams propagating in a turbulent atmosphere through a complex optical system are derived with the help of a tensor method. One finds that the far field...

Continuous generation of dissipative spatial solitons in two-dimensional Ginzburg–Landau models with elliptical shaped potentials被引量：1
《Chinese Optics Letters》2015年第4期72-75,共4页江光裕 刘友文 
supported by the National Natural Science Foundation of China(Nos.11174147,and 11104144);the Fundamental Research Funds for the Central Universities(No.NZ2012301)
We report on the rich dynamics of two-dimensional fundamental solitons coupled and interacting on the top of an elliptical shaped potential in a two-dimensional Ginzburg-Landau model. Under the elliptical shaped poten...

Highly birefringent extruded elliptical-hole photonic crystal fibers with single defect and double defects
《Chinese Optics Letters》2009年第5期387-389,共3页何忠蛟 
supported by the Foundation of Zhejiang Provincial Education Department under Grant No.Y200803144
Highly birefringent elliptical-hole photonic crystal fibers （PCFs） with single defect and double defects are proposed, which are supposed to be achieved by extruding normal circular-hole PCFs based on a triangular-l...
