Abstract
Electromagnetic induction is studied for a two-dimensional earth model where a top conducting layer is underlain by a different tilted conductor, The problem is solved for a small angle of tilt by a successive approximation method, following repeated reflections of electromagnetic energy between the ground surface and the tilted boundary. Two types of field are fonnulated within a conductor, One is characterized by having a vertical component of the magnetic field and the other by having no vertical component of the magnetic field. Both types of field are generated when either type of field arrives at the tilted boundary, It appears that the latter type field plays an important role in producing an anisotropie variation in the electromagnetic field. Solutions are computed numerically on an electronic computer. Severa! exemples of anisotropie behaviour of the electromagnetic field are shown.Keywords
