2D numerical simulation of artificial ionospheric heating in polar region

XU Bin1,2 WANG Zhan-ge1 XUE Kun1 WU Zhen-sen2 WU Jian1 (1. National Key Laboratory of Electromagnetic Environment,China Research Institute of Radiowave Propagation,Qingdao Shandong 266107,China; 2 School of Science,Xidian University,Xi'an Shaanxi 710071,China)  
The 2D numerical simulation model of the ionospheric heating is presented,and the 2D disturbance effect and the saturation characteristic of electron density and temperature are discussed. The density and temperature enhancement of 2D Gaussian distribution,with the beam centre,is produced. The minimum of the density saturation time is located at the position of the increment peak,and the saturation time increases with the range from peak position. The temperature saturation is controlled by background temperature,absorption rate of radio wave energy and thermal conductivity,and has a more complicated space distribution.
