Asymptotic Theory of Generalised Rayleigh Beams and the Dynamic Coupling (2023)
Presentation / Conference Contribution
Nieves, M. J., & Movchan, A. B. (2023, April). Asymptotic Theory of Generalised Rayleigh Beams and the Dynamic Coupling

We consider the effective dynamic response of an infinite asymmetric structure formed from a beam attached to a periodic array of resonators. The array couples the axial and flexural motions of the beam. We develop a point-wise description of the res...

A gyro-elastic device for cloaking of elastic waves in micro-structured materials (2019)
Presentation / Conference Contribution
Garau, M., Nieves, M., Carta, G., & Brun, M. (2019, September). A gyro-elastic device for cloaking of elastic waves in micro-structured materials. Presented at International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS), Rome, Italy

The design of a structured gyro-elastic system capable of being used as a cloaking device for a discrete medium is discussed. The efficiency of the gyro-elastic cloak, composed of springs connecting periodically placed masses, attached to gyroscopic...

Physical Model of a Chiral Flexural Waveguide (2018)
Presentation / Conference Contribution
Carta, G., Nieves, M., Jones, I., Movchan, N., & Movchan, A. (2018, August). Physical Model of a Chiral Flexural Waveguide. Presented at 2018 12th International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials), Espoo

We present a novel physical model of a gyrobeam, an active chiral structural element where flexural and rotational motions are coupled. In the literature, the gyrobeam is described as a mathematical object possessing a continuous distribution of stor... Read More about Physical Model of a Chiral Flexural Waveguide.
