| Abstract: | Digital filter method of evaluating electromagnetic field is presented for a vertical magnetic dipole at the surface or above the homogeneous earth. In the computation,the filtering coefficients by Guptasarma and Singh in 1997 are used and listed in the paper which have two filters for the Hankel J_(0)transform ( 61-point and 120-point) and two filters for Hankel J_(1)transform ( 47-point and 140-point). Some electromagnetic field curves at earth surface due to a vertical magnetic dipole above the homogeneous earth are illustrated. |
