Counterintuitively, under certain critical conditions, weak nonlocality typically exhibited by multilayered dielectric metamaterials may build up strong boundary effects that are not captured by conventional (local) effective-medium models based on simple mixing formulas. Here, we propose an alternative description, based on the trace and anti-trace map formalism, which effectively parameterizes this phenomenon and provides useful physical insight.

Abstract
Counterintuitively, under certain critical conditions, weak nonlocality typically exhibited by multilayered dielectric metamaterials may build up strong boundary effects that are not captured by conventional (local) effective-medium models based on simple mixing formulas. Here, we propose an alternative description, based on the trace and anti-trace map formalism, which effectively parameterizes this phenomenon and provides useful physical insight.File in questo prodotto:
