Anomalous terahertz transmission in bow-tie plasmonic antenna apertures

Anomalous terahertz transmission in bow-tie plasmonic antenna apertures: "Yuping Yang, Ranjan Singh, Weili Zhang
Arrays of subwavelength dipole bow-tie apertures are designed and characterized at terahertz frequencies. For an incident terahertz field perpendicular to the longer axis of the bow tie, a strong resonance enhancement, line narrowing, and a nonmonotonic frequency shift were observed with increasing ...
