Theoretical Study of Magnetohydrodynamic Wave Propagation and Experimental Study of Collisional Effects on Wave Propagation
Abstract
Two problems relevant to the magnetotelluric detection of high altitude nuclear detonations are treated in this report: (1) A computer program is described for solving the poloidal magnetohydrodynamic wave equation with a source current present in a realistic though axisymmetric model of the outer ionosphere. Arguments are given that the poloidal mode of the axisymmetric model should produce the relevant features of a more realistic asymmetric model. (2) The effects of collisions on the propagation of the wave signal through the lower ionosphere is studied experimentally in a laboratory plasma. The facilities constructed for the purpose and the experimental program are described in this report.
