Near-field mapping of complex-valued wavevectors of in-plane hyperbolic phonon polaritons in α-MoO3
Hyperbolic phonon polaritons (HPhPs) in α-phase molybdenum trioxide (α-MoO3) have recently attracted significant attention. They propagate anisotropically along the flake of α-MoO3 and show anomalously concave wavefronts when being excited by a pointlike source. Such anisotropic propagation is gover...
