AI Article Synopsis
- Recent studies show that placing metallic cut-wire arrays near a thin metallic screen can significantly improve the transmission of transverse-electric-polarized electromagnetic fields through small slits.
- This paper presents the first experimental proof of these enhancements using microwave measurements from printed-circuit-board prototypes.
- The experimental findings align closely with numerical predictions and demonstrate that the enhanced transmission remains effective despite potential fabrication errors or imperfections.
Article Abstract
Recent numerical studies have demonstrated the possibility of achieving substantial enhancements in the transmission of transverse-electric-polarized electromagnetic fields through subwavelength slits in a thin metallic screen by placing single or paired metallic cut-wire arrays at a close distance from the screen. In this paper, we report on the first experimental evidence of such extraordinary transmission phenomena, via microwave (X/Ku-band) measurements on printed-circuit-board prototypes. Experimental results agree very well with full-wave numerical predictions, and indicate an intrinsic robustness of the enhanced transmission phenomena with respect to fabrication tolerances and experimental imperfections.
