Control of sound waves through Klein tunnels improves filtering of acoustic signals
Artistic representation of Klein tunnels in phononic crystals. The snowflake pattern represents an etched aluminum nitride membrane that guides sound waves, and the probe symbolizes TMIM technology, which visualizes the movement of waves. Red and blue Dirac cones highlight the transmission of waves through energy barriers without loss. Credit: Yue Jiang In the context of sensory modalities, the eyes function…
