Two-Beam Emitting Via a Single Subwavelength Metal Slit Surrounded by Mixed-Period Dielectric Grooves

Two-Beam Emitting Via a Single Subwavelength Metal Slit Surrounded by Mixed-Period Dielectric Grooves

We use mixed-period dielectric grooves to surround a single metal slit to realize two-beam nonsymmetrical and symmetrical emitting for the transmitted light emerged from the subwavelength slit. This proposed slit-groove-based structure is formed by combining two typical slit-groove structures, both...
