Abstract
A direction-finding device based on coupled and detuned spoof localized surface plasmons, comprising a dielectric substrate with a metal coating at the bottom and two evenly-grooved metal discs with different sizes or materials. The two grooved metal discs represent two spoof localized surface plasmonic resonators, i.e., SLSP1 and SLSP2, with different resonance frequencies due to their different sizes or materials. SLSP1 and SLSP2 are distributed on the dielectric substrate along the diagonal of the dielectric substrate, with the center of the dielectric substrate as a symmetrical center, to form a coupled and detuned spoof localized surface plasmonic system. In response to the incoming waves from different directions, SLSP1 and SLSP2 support spoof localized surface plasmonic modes with different phase differences. According to the phase difference, the incident angle of the incoming waves can be determined uniquely.
