The Field Confinement, Narrow Transmission Resonances, and Green Function of a Multilayered Microsphere with Metamaterial Defects

Abstract EN

We numerically investigate the optical transmission through a compound spherical stack with conventional and metamaterial (MM) layers and also embedded MM defect.

A formation of extremely narrow resonant peak with nearly complete transmittance in area of a band gap is found.

We demonstrate that photon fields of certain frequencies can be strongly confined by a left-handed (LH) defect.

The influence of a random deviation in the width of compound spherical layers as well the transit to the whispering gallery mode (WGM) is also discussed.
