Abstract :
A number of numerical methods are described that have been developed for the characterization, modeling, and design of microwave and millimeter-wave passive structures. Emphasis is on planar and quasiplanar structures. The methods are presented roughly in order of increasing analytical complexity and correspondingly decreasing versatility. The ten methods reviewed are: the finite-difference method, the transmission-line matrix method, the finite-element method, the boundary-element method, the method of moments, the mode-matching technique, the transverse-resonance technique, the spectral-domain method, the method of lines, and the planar circuit approach. Specific advantages and disadvantages in terms of versatility, accuracy, computer time, and memory are discussed. Typical structures are illustrated as representative examples of the methods described.<>
