Abstract
The speed with which electromagnetic energy can be wirelessly transferred from
a source to the user is a crucial parameter for performance of a large number of electronic and
photonic devices. In this presentation we determine the constituent parameters of a medium
which supports theoretically infinite energy concentration close to a medium sample surface;
such a material combines properties of Perfectly Matched Layers (PML) and Double-Negative
(DNG) media. It realizes conjugate matching with free space for every possible mode including,
most importantly, all evanescent modes. We show that extremely high-amplitude resonating
fields in the vicinity of a conjugately matched body can create large far-field radiation with the
use of randomly placed particles which play the role of emission “vessels”.
