USE OF THE FINITE-DIFFERENCE TIME-DOMAIN METHOD FOR CALCULATING EM ABSORPTION IN LOSSY DIELECTRIC SCATTERER

  • 摘要: 本文論述了用時(shí)域有限差分法計(jì)算平面電磁波照射下有耗介質(zhì)中電磁能量的吸收問(wèn)題。討論了影響計(jì)算精度的各種因素。計(jì)算了均勻和分層均勻球體中能量的吸收和分布,并把計(jì)算結(jié)果與精確的解析分析進(jìn)行了比較。還討論了理想導(dǎo)電面的模擬問(wèn)題,并把結(jié)果與鏡象理論進(jìn)行了對(duì)比。所有的結(jié)果都說(shuō)明,在一定條件下,時(shí)域有限差分法能給出滿意的結(jié)果。
    Abstract: The problems for calculating EM energy absorption by lossy dielectric scatterer irradiated by plane wave are discussed. The factors effecting the accuracy of com-putation are discussed. The calculated resuhs of EM energy absorption and its distribution in homogeneous and layered homogeneous lossy dielectric spheres are presented, and the com-parison of these results with analytical soturion is given. The calculation is carried out for dielectric cylinder on conducting ground as well, and the result is compared with the image theory. All the computations show that the finite-difference time-domain method can give satisfactory results.
