WebIsland arcs can either be active or inactive based on their seismicity and presence of volcanoes.Active arcs are ridges of recent volcanoes with an associated deep seismic zone. They also possess a distinct curved form, a chain of active or recently extinct volcanoes, a deep-sea trench, and a large negative Bouguer anomaly on the convex side of the volcanic … WebPhysical Optics (PO) approximation and using a near-field RCS definition, this communication presents high frequency analytical formulas to calculate monostatic RCS of perfectly-conducting flat circular and square plates, when these objects are observed in near-field for normal and oblique incidences.
