R. Elsasser et al., FINITE-ELEMENT INVESTIGATIONS OF THE DYNAMICAL PROPERTIES OF MICROSTRUCTURED MEMBRANES, Microsystem technologies, 3(4), 1997, pp. 171-177
Microstructured membranes (microdiaphragms) are a tool for measuring q
uantities such as temperature, strain, or density by ultrasound, i.e.
without any contact (e.g. by a wire connection). In this paper we stud
y the dynamical properties of such microstructured membranes numerical
ly by means of the finite element method. In particular, we consider t
he shape of the eigenmodes of the system and study the dependence of t
he corresponding eigenfrequencies on material and geometry parameters.
