Leaky Wave Antenna by Spin Photonic Topological Insulators Using 30-degree rhombic unit cell

Published 6 Mar 2023 in physics.app-ph | (2303.07117v2)

Abstract: A new spin photonic topological insulator model with a 30-degree rhombic unit cell is presented and analyzed. Topological band gaps and the robustness against the defects are shown. The edge modes are studied via full-wave simulation of a ribbon of unit cells. By using the structure in the fast wave region, a leaky wave antenna is proposed with a gain of 18.2dB.
