The present work re-evaluates the stability analysis in a mixing layer/wake interaction where experimentsrnindicate the presence of two distinct fundamental frequencies. The origin and reason for this phenomenon is due tornmultiple self-excitation frequency found in the near field. To the author best knowledge, such results were never beforernpresented for significant physical flows in the literature
