Abstract
Electromagnetic (EM) eigen modes in a flshnet metamate- rial (MM) slab have been comprehensively analyzed in an experimental conflguration, based only on precise solutions of Maxwell equations. The EM eigen modes were directly detected from light-absorption peaks. Each mode was explicitly characterized by the dispersion di- agram and EM fleld distributions. It was consequently found that the modes were classifled into either inner modes inside the slab or a mode at the interface with the surrounding media. The symmetric properties of the inner modes were clarifled using group theory. The in- terface mode was found to come from surface plasmon polariton at ∞at metal/insulator interface. The present analysis procedure is generally applicable to MM slabs and enables to clarify the properties without models or assumptions, which have been usually used in MM studies.
