- Abstract
Flat-top transmission bands are found in a plasmonic structure constructed by periodic ring resonators. Fabry-Perot effects can be suppressed in a set of parameters determined by an effective medium method. Two kinds of transmission bands with flat-top profiles can emerge due to either ring resonance or Bragg scattering. These bands are both red shifted when the distance of rings increases. Both transfer matrix method and finite difference time domain method are utilized to investigate the flat-top bands. The proposed structure can be employed as a plasmonic band-pass filter and might be useful in the field of integrated optoelectronics.
