Abstract

A new multiresonant metamaterial composed of asymmetric triangular electromagnetic resonators (ATERs) is presented in this letter. The ATERs´ structure has one electric resonance and two magnetic resonances. The parametric retrieval and eigenmode analysis based on simulations and experiments are utilized to gain an insight into the resonance mechanisms. A parallel-plate waveguide (PPW) measurement system is introduced to detect the characteristics of multiresonant ATERs. The transmission stopband obtained by the PPW system effectively reveals that one resonance is caused by an electric mode and the other two resonances are caused by magnetic modes.
