| Abstract: | The reflectivity MT method, an entirrely new method of MT data analysis, is similar to that of reflecrtion seismic. In this paper, the authors show the U-transform of the pseu-do-impule response of seismic wave in time domain, in order to analyze pseudo-impulse of the multi-layered media. This method provides new approach for processing MT and interpretation technique. The authors have discussed propagation character and pseudo-impulse of EM wave in the lossy and dielectric media. Analytical solution for the two-layered earth model show the theory of the U-transform of the pseudo-impulse holds. |
