Thin perfect absorbers based on metamaterials for optical frequencies

In this work a bidimensional array of particles is approached like a system of dipoles characterized by their electric and magnetic polarizabilities. The interaction between particles has been taken into account by adding contribution of every dipole at the position of the central dipole. This array...

Posteriormente se modeló el arreglo como una superficie que soporta corrientes superficiales eléctricas y magnéticas efectivas. Con dichas corrientes se establecieron las condiciones de frontera necesarias para obtener absorción perfecta.
