image: Figure 1. Schematic of imaging under real-frequency and synthesised complex frequency excitation in a superlens. The same object, when imaged through a superlens under different real-frequency ...
Figure 1Schematic of polariton propagations under real frequency and synthesized complex frequency excitation. While polariton waves at real frequencies have limited propagation distance, combining ...
Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.
