The forbidden propagation of hyperbolic phonon polaritons and applications in near-field energy transport
Schematic illustrations of (a) experimental setup for the GHz burst LIPAA process, (b) a pulse form of GHz burst mode containing P intra-pulses, and the measured waveforms of (c) a GHz burst pulse with 10 intra-pulse numbers and (d) a pulse at the single-pulse mode operation as comparison.
