Abstract

We perform a detailed study of the phenomenon of resonant absorption that occurs at an oblique incidence in the vicinity of the zero refractive index transition in graded index metamaterials with the refractive index changing from positive to negative values. We compare the results of numerical simulations with analytical predictions for the case of the linear gradient index profile. Furthermore, we numerically study the transition phenomena in graded index layers with more complex index profiles. A detailed understanding of the phenomenon of resonant absorption may be of considerable importance in the context of transformation optics as it strongly modifies the field distribution near the zero index transition.
