An efficient semi-numeric model for a novel miniaturized membrane-rheometer

A recently introduced membrane rheometer consisting of a sample cell covered with two Lorentz force actuated membranes is modeled using a spectral Fourier transform method yielding a semi-numerical solution. This solution presented here efficiently delivers valuable properties like frequency responses, penetration depths of shear waves, and power dissipation regimes. Furthermore this novel concept enables the designer to simulate the behavior of the system under varying setup parameters in order to obtain an optimum setup for the given measurement problem.
