'DARK' MODES BACKSCATTERING AS POSSIBLE RATIONALE FOR ANOMALOUS RETROREFLECTION FROM STRONGLY ABSORBING POROUS NANOSTRUCTURES

摘要

The previously discovered anomalous retroreflection in a strongly absorbing nanostructured medium is explained by using "dark" and "bright" modes. The consideration provides rationale not only for the retroreflection itself but explains correlations with absorption and differences for s- and p-polarized radiation retroreflection.
