Magnetically switchable 1×3 demultiplexer based on Terfenol-D-integrated phononic crystal ring resonators

Key Points

• Efficient demultiplexing occurs, successfully redirecting acoustic signals between three outputs.
• The device operates within a frequency range of 1-3 kHz, demonstrating a response time of under 100 ms.
• Analysis involves integrated Terfenol-D within phononic crystal ring resonators to enhance signal control.
• The findings may enable innovative applications in telecommunications and signal processing.
