Abstract:

An exact expression is obtained for the field of a horizontal Hertz dipole moving around a conducting sphere in a circular orbit. This expression is in the form of a double series which, in the case of a large sphere, is evaluated by the method of Watson transformation. The geometrical optics field is separated out and its properties examined. It is found that the incident and reflected waves are of different frequencies.
