| Abstract: | A new method for computing the electromagnetic field due to dipole antenna instratified media is proposed.The general form and essential performances of the integralsolution of the electromagnetic field are described.To evaluate these integrals theFourier-Hankel transform(FHT)algorithm and the Fast Fourier-Hankel transform(FFHT)algorithm are introduced.Some simulated responses of induction logging tools obtained withthis method are presented.The examples illustrated its good application. |
