This paper presents a model of interface reflection interference in order to determine matching frequency and thickness with minimum reflection loss. It is found that a proper combination of the frontface reflection and back-face reflection is necessary to produce perfect matching, which leads to global minimum reflection loss. The calculated amplitude differences of the front-face reflection and back-face reflection from the derived formula agree well with the intensity variation of the microwave matching absorbing peak.
