| 摘 要： | 由于各向异性等离子体介质中的介质参数是张量形式,而在各向同性介质中为标量形式,故在研究各向异性等离子体与电磁波的相互作用与分析各向同性媒质的方法就不同.采用线性插值的方法给出各向异性等离子体介质中的FDTD离散式,编写了程序并进行了数值计算,给出与解析方法比较结果,两者符合的很好,并给出等离子体球的电磁散射的若干算例.结果可应用于等离子体的电波传播、天线等领域.

| Abstract: | The difference between these two media is their medium parameters,which are scalar quantity in isotropic medium and tensor in plasma anisotropic media.And the method of analysis between electromagnetic wave and plasma anisotropic medium isn't similar to that of between electromagnetic wave and isotropic medium.The linear interpolation scheme for plasma anisotropic medium have been used in this paper.Some results can be given,and one special case is given between the present method and the analytical solution and a very good agreement is found as we expected.The method presented in this paper can be used in the space of radiowave propagation in plasma anisotropic medium,antenna and other cases. |
