Railway noise: auralization of the sound radiated from wheel and rail
acoustics, auralization, curve squeal, noise synthesis, Railway noise, vehicle dynamics, Wheel-Rail interactionNoise generated by rail vehicles has become an issue of increasing concern, particularly in urban and interurban contexts where the demand for sustainable and efficient mobility has driven the expansion of rail networks. This has led, in recent years, to the development of several methodologies aimed at predicting the noise generated by wheel–rail interaction. However,

Railway noise: modelling sound radiation from wheel and rail
Noise generated by rail vehicles has become an issue of increasing concern, particularly in urban and interurban contexts where the demand for sustainable and efficient mobility has driven the expansion of rail networks. Consequently, there is a growing need to optimise vehicle design and component performance to comply with stringent regulatory requirements and to enhance

3D acoustic invisibility cloak
Acoustic metamaterials gave birth to the engineering counterpart of amazing cutting-edge novelties from physics, which discovered and proved unusual ways for steering pressure waves. Outcomes such as superlensing and invisibility cloaking are the most famous and impressive applications. However, the practical realization of these applications remains a significant challenge. Our research group is dedicated to

Transcranial focused ultrasound via metamaterial engineering
DETAILS: the aim of this project is to study a metamaterial structure capable of focusing ultrasound from outside to the inside the skull. In this field, the state-of-the-art ultrasound technology features a hemispherical transducer array with many piezoelectric elements operating around a central frequency of 650 kHz. By leveraging complex electronic circuits the system allows
