Abstract
Here, theoretically we uncover two topological transitions of the wave dispersion at midinfrared frequencies in a wire medium formed by lithium tantalate nanowires. We show while one transition is fixed at one certain frequency, the other transition happening at lower frequency can be blue shifted which enables to achieve a broadband enhancement of emission for an infrared emitter embedded into the medium.
