Calculation of Lightning Electromagnetic Fields: a Review
Lightning return stroke is a self-propagating discharge with path length measured in kilometres, which extends at high speeds, sometimes approaching a significant fraction of the speed of light. Usually one is interested in the electromagnetic fields produced by lightning several tens of meters to some kilometres away. In order to calculate fields from lightning, it is modelled as a linear trav...
متن کاملLightning Electromagnetic Fields: Modeling and Measurements
All lightning processes, in both cloud and cloud-toground discharges, are associated with the motion of charges an& as a result, produce electromagnetic fields. Only one (presumably the most important from an EMC point of view) process, the return stroke in cloud-toground lightn& is considered in this review. There are basically four levels of sophistication in the mathematical modeling of the ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولEffect of Nearby Buildings on Electromagnetic Fields from Lightning
We present a discussion on the effect of nearby buildings on the electric and magnetic fields radiated by lightning. Electric and magnetic fields radiated from distant natural lightning have been measured simultaneously on the roof of a building (the Power Systems Laboratory of the Swiss Federal Institute of Technology, Lausanne, Switzerland) and on the ground at different distances away from i...
متن کاملHow the Nonextensivity Parameter Affects Energy Fluctuations
In this article, the effect of the nonextensivity parameter on the energy fluctuations of nonextensive systems is studied in two different versions of the Tsallis statistical mechanics. Once a general expression has been reported for the energy fluctuations in the second version (Tsallis work in 1988), the energy fluctuations of an ideal gas and a harmonic oscillator are studied in the second a...
