Abstract :
We derive periodic multilayer absorbers with effective uniaxial properties similar to a perfectly matched layer (PML). This approximate representation of a PML is based on effective medium theory, and we call it an effective medium PML (EM-PML). We also show that cylindrical core-shell nanostructures derived from flat multilayers also exhibit very good absorptive and reflective properties despite the different geometry.
