Electromagnetic-acoustic splitter with a tunable splitting ratio based on copper plates

Area of Science:

• Physics
• Engineering
• Materials Science

Background:

• Acoustic and electromagnetic splitters are crucial in navigation and interference detection.
• Existing splitters lack the capability for simultaneous acoustic and electromagnetic beam splitting.
• A need exists for integrated devices that can handle both wave types.

Purpose of the Study:

• To propose and investigate a novel electromagnetic-acoustic splitter (EAS).
• To achieve simultaneous and identical beam-splitting for transverse magnetic (TM)-polarized electromagnetic and acoustic waves.
• To enable a tunable splitting ratio without additional energy consumption.

Main Methods:

• Design of a novel EAS structure using copper plates.
• Simulations to verify the beam-splitting performance for both electromagnetic and acoustic waves.
• Analysis of the tunable splitting ratio mechanism via incident angle adjustment.

Main Results:

• The proposed EAS successfully demonstrates simultaneous beam splitting for TM-polarized electromagnetic and acoustic waves.
• A tunable splitting ratio is achieved by simply altering the incident angle of the input beam.
• Simulated results confirm the creation of two transmitted split beams with controllable ratios for both wave types.

Conclusions:

• The developed passive EAS offers a unique solution for simultaneous dual-field wave splitting.
• Tunable splitting ratios enhance the adaptability of the device for various applications.
• Potential applications in dual-field navigation and detection promise improved accuracy and information richness.
