文摘In this article, the fast multipole method （FMM） is applied to analgze the field strength of an ultra-wideband （UWB） signal. Small coverage of UWB communication systems and high efficiency of the algorithm make it possible to calculate the amplitude of electric field accurately. A homogeneous dielectric body and a multilayered dielectric object are studied. The computational results obtained by applying the FMM agree well with those obtained by applying the method of moments （MoM）.
