Abstract:

The magnitude of the slope of skewed isophasor lines from electromagnetic emitters is shown to be directly related to the physical distance between the geometric center of the spatially distributed electromagnetic emitters and the projected phase cebter obtained by extrapolation of the skewed isophasor lines. It is shown that the slope of the iosphasor lines not only depends on the excitations of the electromagnetic emitters but also on the inter-emitter spacing. Finally, an optimization method is utilized to obtain the excitations for a set of spatially distributed electromagnetic emitters for a specified slope of the iosphasor lines, a fixed number of electromagnetic emitters and for a given minimum inter-emitter spacing.
