Deep-Subwavelength Focusing and Steering of Light in an Aperiodic Metallic Waveguide Array
Deep-Subwavelength Focusing Light Aperiodic Metallic Waveguide Array
2015/8/10
We consider an aperiodic array of coupled metallic waveguides with varying subwavelength widths.For an incident plane wave, we numerically demonstrate that a focus of as small as one-hundredth of a wa...
