چکیده
|
Enhancement of magneto-optical response by coupling of propagating with localized plasmons in a structure based on silver and bismuth-substituted ferrite garnet has been numerically studied. it is shown that the absolute value of the magneto-optical response in the examined structure reaches a high value of 0.04, and the structure has a reflection coefficient sufficiently high for a number of practical applications. the strong coupling between localized and propagating plasmons, which caused the significant enhancement of the magneto-optical response, was manifested in the reflection spectrum of the structure in the form of an asymmetric fano-like resonance. the proposed structure, intended for operation in the near infrared range, is a promising one for solving various problems in magnonics and bionanophotonics.
