'Simplified' VLF/LF Mode Conversion Computer Programs: GRNDMC and ARBNMC.
Abstract
The computer programs GRNDMC and ARBNMC numerically determine vlf/lf mode conversion coefficients and mode sums for an earth-ionosphere waveguide which is inhomogeneous along the direction of propagation. GRNDMC generates values of the vertical electric field, Ez, at the ground as produced by a ground based vertical dipole source, ARBNMC calculates at an arbitrary height within the guide, all three electric field components (Ez, Ex and Ey) generated by an electric dipole of arbitrary orientation and height within the guide. The ARBNMC program treats air-to-air, ground-to-air or air-to-ground vlf/lf problems. It will also handle ground-to-ground propagation but is much less economical to run than GRNDMC. (Autor)
