Abstract

Presents the design of a W-band LiGA (a German acronym for lithographe, galvanoformung, und abformung) fabricated three-dimensional five-gap coupled cavity. This paper focuses on analyzing the coupling slot effects on such a periodic structure´s dispersion characteristics using the three-dimensional code MAFIA (Maxwell equation using finite integration algorithm). The different coupling slot sizes corresponding to LiGA fabrication and EDM (electric discharge machining) fabrication constraints have been modeled and discussed in detail. The equivalent circuit model of such a coupling slot in two-dimensional MAGIC code also has been studied.
