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.<>
