Transverse magneto-photonic transmission effect in non-symmetric nanostructures with comb-like plasmonic gratings

Spatial symmetry breaking in the magnetoplasmonic system results in magneto optical effects prohibited in symmetric structures. The transverse magneto-photonic transmission effect (TMPTE), occurs thereby, which is characterized by a non-zero transmission dependency on magnetism at normal incidence of light. This phenomenon is due to inequality of the forward and backward surface plasmon polariton (SPP) waves at the metal/dielectric interface in non-symmetric plasmonic grating. Here we investigate the TMPTE in magnetoplasmonic nanostructures with comb-like gratings and explore how to optimize its parameters for the magnitude of the effect.

Automated summary

Spatial symmetry breaking in magnetoplasmonic systems leads to magneto optical effects that are not allowed in symmetric structures. The transverse magneto-photonic transmission effect (TMPTE) occurs as a result of the inequality between the forward and backward surface plasmon polariton waves at the metal/dielectric interface in non-symmetric plasmonic gratings.
