Line-waves (LWs) are highly confined one-dimensional electromagnetic modes that propagate along the interface between complementary metasurfaces and offer a promising platform for overcoming the inherent limitations of conventional power dividers. Traditional structures, such as Wilkinson power dividers, often suffer from narrow bandwidth, high insertion loss, and limited power handling capability, which restrict their performance in modern radio frequency (RF) and microwave systems. In this work, we propose a compact topolog-ical T-shaped (1×2) power divider that leverages complementary inductive–capacitive metasurfaces in conjunction with dielectric loading. The complementary metasurfaces enable the coexistence of TM and TE surface modes, while the dielectric loading significantly enhances field confinement and impedance matching across a broad frequency range. Therefore, the proposed design achieves low loss, high power transfer efficiency, and broadband operation. The presented structure offers a scalable solution that addresses key challenges in RF and microwave circuitry, providing an effective approach for next-generation signal distribution networks.
