Second-harmonic generation (SHG) and other second-order nonlinear processes do not occur in bulk gold due
to its centrosymmetric crystal structure. However, the centrosymmetry is broken at the surface, giving rise to
non-zero surface susceptibility tensor ...
Each one of the billions of smartphones on the planet contains some acoustic filter for signal routing and processing, commonly made with Surface Acoustic Wave (SAW) or Bulk Acoustic Wave (BAW) resonators.
The frequency of a SAW resonator can be easily set ...
Dielectric Elastomer Actuators (DEAs) are recent type of smart materials, which transform electric energy into mechanical work. They show impressive performance as soft actuators. Capable of multidirectional actuation, large strain and high energy density, ...
