THE METHOD OF MATRIX-ORDER REDUCTION AND ITS APPLICATIONS TO ELECTROMAGNETIC PROBLEMS

A new numerical technique, termed the method of matrix-order reduction (MMOR), is developed for handling electromagnetic problems in this pa per, in which the matrix equation resulted from a method-of-moments an alysis is converted either to an eigenvalue equation or to another mat rix equation with the matrix order in both cases being much reduced, a nd also, the accuracy of solution obtained by solving either of above equations is improved by means of a newly proposed generalized Jacobia n iteration. As a result, this technique enjoys the advantages of less computational expenses and a relatively good solution accuracy as wel l. To testify this new technique, a number of wire antennas are examin ed and the calculated results are compared with those obtained by usin g the method of moments.
