Title :
Complex image theory-revisited
Abstract :
A quasi-historical sketch of complex image theory for low-frequency electromagnetic fields is presented from a personal perspective. Studies using complex image theory, on launching TM (transverse magnetic) modes into the Earth-ionosphere waveguide from a horizontal insulated cable, grounded at the end points, are described. Subsequent implementation and further development of the concept by other authors is summarized.<>
