Few-mode fiber is a significant component of free-space optical communication at the receiver to obtain achievable high coupling efficiency. A theoretical model from link few-mode proposed based on scale-adapted set Laguerre-Gaussian modes. It found that efficiency various modes behaves differently in presence atmospheric turbulence or random jitter. Based this model, optimal geometry parameter...

this paper is a part of study about the impact of the microclimate on the space use and the user’s behaviours. the purpose of our study is to get an in-depth understanding of how people use out door public spaces in different climatic conditions, how their behaviour and perception of the space change with the climatic variations. we have employed a multi-method approach which combines a “qualit...
