摘要: We propose a splitter feeding network for array radiations of spoof surface plasmon polaritons (SPPs), which are guided by ultrathin corrugated metallic strips. Based on the coupled mode theory, SPP fields along single waveguide in certain frequency range can be readily into two adjacent branch waveguides with same propagation constants. to load U-shaped particles anti-symmetrically at ends such waveguides, showing high integration degree network. By controlling linear phase modulations produced particle chain, we demonstrate theoretically and experimentally that based bound modes efficiently radiated far broadside direction. The proposed method shows symmetry electromagnetic field exploited transmission network, providing potential solutions compact power dividers combiners microwave optical devices systems.
