Spatial filters in structural control

This paper discusses the use of modal filters in structural control. Discrete piezoelectric array sensors are first discussed and their lack of roll-off due to spatial aliasing is pointed out. In the second part, a new porous distributed electrode concept is introduced, which allows the effective piezoelectric coefficient to be tailored in two dimensions.
