Abstract

Abstract : The concept of ionospheric modifications is a part of a much more common class of research today known as "Active Experiments" in auroral plasma. The interaction of High power electromagnetic Radio waves with auroral plasma is one of that field which has been have been investigated by this study. Plasma in that auroral region might be illuminated via electromagnetic waves for a prolonged period and therefore, undergo accumulative resonances and perturbations due to its slow transport rates, weak convection and long lifetime of plasma, mainly nearby the peak of profile of ionospheric electron density. A plasma can be resonance at a particular height in the ionosphere includes a equivalent electromagnetic wave frequency. These types of plasma resonances are able to improve the local fields of electromagnetic, and as a result their interactions with plasma particles causing density perturbations, turbulences, field aligned striations and local heating. These kinds of effects will be more obvious when the electromagnetic wave frequency is close to foF2, the resonance frequency nearby the peak of the profile of ionospheric electron density. Optical emissions may also be enhanced during such conditions. This work aim to investigate the interaction of EM with ionosphere layers D, E and F. The simulation model run under COMSOL Multiphasic software. The EM selected to be at 10MHz and 2.4GH, the electron density has been taken to be (10 8 , 10 10 and 10 11 ) for D, E, F ionospheric layers respectively. The simulation results have been recorded and analyzed for: electron temperature of plasma, electron density of plasma, electric potential of plasms, resistive losses, electric field norm and the relation between the input port power and the time. The results provide a clear and important information about interaction of EM with ionosphere that can help to predicate there transmission and its range for many purpose.
电磁波与电离层相互作用的等离子体物理方法
摘要:电离层变化的概念是今天在极光等离子体中被称为“主动实验”的更常见的一类研究的一部分。大功率电磁无线电波与极光等离子体的相互作用是本研究研究的领域之一。该极光区等离子体受电磁波照射的时间较长,传输速率慢,对流弱,寿命长,主要分布在电离层电子密度剖面峰值附近,因此存在累积共振和扰动。等离子体可以在电离层的特定高度共振,其中包括等效的电磁波频率。这些类型的等离子体共振能够改善局部电磁场,并且由于它们与等离子体粒子的相互作用导致密度扰动、湍流、场对准条纹和局部加热。当电磁波频率接近电离层电子密度剖面峰值附近的共振频率foF2时,这些效应更为明显。在这种条件下,光发射也可能增强。本文旨在研究电磁与电离层D、E和f的相互作用。模拟模型在COMSOL Multiphasic软件下运行。电离层D层、E层、F层的电子密度分别为(10 8、10 10和10 11)。记录并分析了仿真结果:等离子体电子温度、等离子体电子密度、等离子体电势、电阻损耗、电场范数以及输入端口功率与时间的关系。结果提供了电磁与电离层相互作用的清晰而重要的信息,有助于预测电离层的传输及其范围。
