•A proper combination of the front-face reflection and back-face reflection is necessary to produce the perfect matching condition;•This model can explain the variation of minimum RL peak intensity for every thicknesses;•At the perfect matching thickness, the amplitude of front-face reflection ΓΓ is equal to the amplitude of back-face reflection ΠΠ;•The perfect matching condition can be designed by controlling the sendust volume fraction in the composites.
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 front-face 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.
