Abstract-- Derivation of the closed-form Green's functions
and analytical evaluation of the method of moments (MOM)
matrix entries have improved the computational efficiency of
the significantly in the analysis of printed geometries. With this
background in mind, an extension of this efficient numerical tech-
nique is to incorporate an optimization algorithm and to assess its
potential as a computer-aided design (CAD) tool. Therefore, we
have employed the Gradient search and Genetic algorithms, in
conjunction with the electromagnetic (EM) simulation technique,
to a number of representative examples of interest.
Index Terms--Green's functions, method of moments, printed
antennas.
