Generation of Wide-Band Data from MM-PO Hybrid Method by [Z] Matrix Interpolation

In this paper, we report the results of extensive numerical investigation via MM-PO of several canonical structures in the form of an antenna radiating in the presence of electrically large conducting object. The goal of the investigation is to reveal the frequency variations of the elements of MM-PO impedance matrix for the purpose of optimising the matrix interpolation procedure, and finally to explore a possibility of generating wide-band data from MM-PO by [Z] matrix interpolation. Sample numerical results clearly demonstrate usefulness and efficiency of the overall approach.
