Normalized simulated transient rotating electric dipole spectrum. Calculated frequency spectrum for transient rotating dipole lasting ½ of a full orbital period. The designed target frequency (green) is recovered in the transient dipole model. In addition, the peak emission occurs at a normalized frequency at ~ 1.36 (red). A secondary peak occurs at ~ 3.6.
