Dirac Leaky Wave Antennas

2018 Fifth International Conference on Millimeter-Wave and Terahertz Technologies (MMWaTT), 2018
Dirac leaky-wave antennas (DLWAs) are derived from photonic crystals exhibiting Dirac cone dispersion around their $\Gamma$-point. DLWAs provide high directive beams and continuous frequency beam scanning, non-fluctuating leakage constant and real non-zero Bloch impedance at and around broadside, due to the closed and linear Dirac dispersion relation ...
