Abstract :
A moment method using a dyadic Green´s function is developed for the analysis of quasi-optical systems. The dyadic Green´s function used has separate terms for the paraxial and non-paraxial fields and is much easier to develop than a mixed potential Green´s function. The method is applied to the analysis of antenna elements in a quasi-optical resonator.<>
