Abstract

The modified diakoptic theory is described, and its relationship to the method of moments is explained. Utilization of the theory is illustrated by an example application of the simple curved-wire antenna. A numerically efficient iteration method for computing open-port currents on a structure is outlined, as is the use of these currents to obtain open-port impedance elements characteristic of the diakopted structure. It is pointed out that the rank of the diakoptic matrix is far smaller than that of the moment-method matrix. For those antennas and circuits to which the modified diakoptic theory is applicable, the lower rank of the matrix admits greater numerical efficiency in complex and/or large structures.<>
