THE GRADIENT ASSOCIATED CONJUGATE DIRECTION METHOD

Abstract

A new conjugate direction (CD) based method, GaCD by name, is addressed with its full derivations. Comparison with some commonly used CD methods is made, concluding that the GaCD method is among the best of them, in terms of an assessment number. A practical example is presented in which a waveguide-microstrip transition section is optimized with respect to its transmission parameter S2l. The measurement of the transition agrees very well with the numerical results. [Vol. 11, No. 3 (1996), pp 82-96]
