Project publication · Forum Acusticum / EuroNoise 2025
Summary
The conference paper presents the design, fabrication and experimental characterization of an acoustic leaky-wave antenna for underwater applications. The structure uses low-cost materials and a single transducer to steer the acoustic beam according to the operating frequency.
Main contribution
The work combines finite-element simulation, material selection and experimental validation to verify that the antenna can scan the acoustic beam from backward to forward directions. This capability opens the way to compact solutions for localization, SONAR and underwater acoustic communications.
Resultados y alcance
Las simulaciones por elementos finitos y los ensayos experimentales confirman la exploración angular de la antena al variar la frecuencia, incluyendo radiación hacia atrás, lateral y hacia delante. La correspondencia entre modelo y prototipo valida el concepto, cuyo rendimiento final depende de materiales, fabricación y acoplamiento del transductor.
Link with BoND1
BoND1 addresses non-cellular connectivity and IoT scenarios where propagation, efficiency and scalability shape network design. This conference paper adds a complementary contribution from the acoustic domain: spatial link control, low-cost prototyping and experimental validation of a technology useful for communications and sensing in difficult environments.
