Abstract :
An analytical model is proposed to fully characterize the modal structure of 3D metamaterial cavities which can be used to improve the properties of reverberation chambers. The metamaterials are modelled by a complex reflection coefficient. We discuss the valid ranges of indices of the resonant frequencies as function of the phase of reflection coefficients. A set of rules for counting the number of modes is proposed. Using numerical simulations, the number and the density of modes when using different reflection coefficients are evaluated.
