Abstract
Given a specified form, both in time and space, for the electromagneti c fields on the axis of a lossy cylinder, we determine, analytically, the required azimuthally symmetric source distribution on the surface of the cylinder that generates such internal fields. We then show that this source is equivalent to an array with finite number of cylindric al slots in a metal encasing that are impulsed by specified voltages a t a finite sequence of discrete times. A confirming forward calculatio n exhibits excellent agreement between the specified field form and th at generated by the array of cylindrical slots. Potential applications are to hyperthermic cancer therapy, bioelectromagnetics and nondestru ctive testing.
