研究目的
To modulate the surface impedances of surface plasmon polaritons for directional leaky wave emission from hybrid plasmonic waveguides.
研究成果
The proposed plasmonic leaky wave nanoantenna, designed with surface impedance modulation theory, achieves a wide-angle beam scanning of over 90° with a peak directivity of 19 dBi, demonstrating its potential for plasmonic circuit and applications.
研究不足
The high transmission loss of SPPs and the practical challenges in designing SPP-based feeding networks are noted limitations.
