Rigorous Computation of Large Radiation Problems by Means of an Iterative Approach

摘要

In this work, we present a numerical technique for the analysis of the radiation pattern of antennas which interact with complex structures. For this purpose we isolate different parts of the geometry and obtain the primary currents taking into account the external excitations. Next, we compute the interactions between different parts of the geometry and update the total currents. This method is especially well suited for problems that lie beyond the scope of both rigorous and high-frequency conventional techniques, due to computational and/or accuracy requirements.
