Abstract

In this paper some mistakes arising in Singh and Mogi (2010) that are: (1) wrong formulation of the intrinsic impedance of the layers of an N-layered earth(Zi) and reflection coefficient of the EM wave in TM-mode (rTM), (2) using wrong and the very same algorithms for computing reflection coefficients of the EM wave in both the TE-and the TM-mode(rTE and rTM) and(3)using flawed algorithms for computing phase and normalized phase values, relating to electric and magnetic components of the EM wave, are noted and corrected form of these mistakes are presented. Moreover, in order to illustrate how these mistakes can affect forward modeling results different two-and three-layered earth models, the same as the models used in Singh and Mogi(2010), are chosen; afterwards EMDPLER and corrected version of this program, presented in this paper titled "EMDPLER_Corr", are conducted on these models and real and imaginary parts of Hz and Hy components of the magnetic field intensity, their normalized amplitudes (|H z/ H z0 | and |Hy / | Hy0 |) and the corresponding normalized phases are computed, plotted versus frequency and compared with each other.
