Abstract

Abstract : In article number 2002014, Peng Gao and co‐workers use an electron probe to selectively excite hyperbolic phonon polaritons in multiple frequency bands covering both the mid‐ and far‐infrared in α‐MoO3 . The broad‐spectral‐range sustainability together with highly anisotropic excitation and propagation behavior of these polaritons may find potential applications in nanoscale confinement and manipulation of light.
