In this paper, we present a highly efficient computational electromagnetics technique for wide-band analysis of antennas radiating in the presence of electrically large conducting bodies (platforms). The technique is based upon the well known moment method-physical optics (MM-PO) hybrid formulation combined with the impedance matrix interpolation and a dynamic adaptive frequency sampling of the desired observable. Numerical examples are given to demonstrate considerable saving in both computer memory and CPU time offered by the proposed approach.
