Phononic graded meta-MEMS for elastic wave amplification and filtering
Federico Maspero, Jacopo Maria De Ponti, Luca Iorio +5
Inspired by recent graded metamaterials designs, we create phononic arrays of micro-resonators for frequency signal amplification and wave filtering. Leveraging suspended waveguide…
Three-dimensional spin-wave dynamics, localization and interference in a synthetic antiferromagnet
Davide Girardi, Simone Finizio, Claire Donnelly +8
Spin waves are collective perturbations in the orientation of the magnetic moments in magnetically ordered materials. Their rich phenomenology is intrinsically three-dimensional; h…
Roton-like dispersion via polarisation change for elastic wave energy control in graded delay-lines
Luca Iorio, Jacopo Maria De Ponti, Federico Maspero +1
While roton dispersion relations had been restricted to correlated quantum systems at low temperature, recent works show the possibility of obtaining this unusual dispersion in aco…
MEMS Magnetometer Using Magnetic Flux Concentrators and Permanent Magnets
Federico Maspero, Gabriele Gatani, Simone Cuccurullo +1
A novel frequency modulated MEMS magnetometer is presented. The new device is inspired by the magnetic force microscopy technique, it combines standard MEMS technology with magneti…
Impact of magnetic domains on magnetic flux concentrators
Federico Maspero, Simone Cuccurullo, Dhavalkumar Mungpara +2
The impact of magnetic domains in magnetic flux concentrators is studied using the simulation software MuMax3. First, the simulation parameters are validated using experimental res…
