Abstract :
A phononic crystal device is investigated as a sensor platform combining bandgap engineering with resonant transmission. Here we apply a regular phononic crystal with a solid matrix and liquid filled holes, fully immersed into the liquid with incidence direction of sound normal to the plate.
