Periodic metal-dielectric structures attract substantial interest since it was previously proposed that the spontaneous emission amplification rates (the Purcell factor) in such structures can reach enormous values up to 105. However, the role of abs... Read More about Revising of the Purcell effect in periodic metal-dielectric structures: the role of absorption.
