Attenuation of Electromagnetic Waves by Vegetation
An analytical overview of research involving EM waves attenuation by vegetation canopies in the frequency range 100...10000 MHz is given. Brief descriptions of objects of investigation and typical biometric features are presented. The models of vegetation as a continuous medium and as a collection of scatterers are considered. Dielectric properties of vegetative material are discussed. The rela...
متن کاملA Review on Rain Attenuation of Radio Waves
Water is naturally found in atmosphere in three major physical states as: liquid (rain, fog & clouds), solid (snow flakes, ice-crystals) & gaseous (water vapors). In any of the forms the occurrence of water causes hindrances in the path of radio waves in form of absorption & scattering leading to some loss in signal quality & quantity both which is quantified in terms of attenuation. Here we pr...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولPrediction of Rain Attenuation Series with Discretized Spectral Model
The rain attenuation plays a major role in the design of satellite-to-earth links operating at high frequencies such as Ka band and Ku band. The signal suffers from a strong attenuation during the propagation path as raindrops absorb and scatter radio waves, which results in an increase of transmission error and reduction of the system availability [1]. Predicting rain attenuation is one of the...
