Extraordinary optical absorption through subwavelength slits
Extraordinary optical subwavelength slits
2015/8/10
We report on the ability of resonant plasmonic slits to efficiently concentrate electromagnetic energy into a nanoscale volume of absorbing material placed inside or directly behind the slit. Th...
Transmission Properties of Metallic Grating with Subwavelength Slits in THz Frequency Region
Transmission Properties Metallic Grating Subwavelength Slits THz Frequency Region
2010/12/6
This paper presents a fully experimental and theoretical study on transmission properties of a deep metallic grating with subwavelength slits in THz frequency region by using THz time domain spectrosc...
Guided modes supported by plasmonic films with a periodic arrangement of subwavelength slits
periodic arrangement subwavelength slits
2015/8/11
We calculate the guided band diagram of a metallic film with a one-dimensional periodic arrangement of cut-through subwavelength slits. We find that this system supports two distinct types...
