Characterization of a novel membrane-rheometer utilizing a semi-numerical modelling approach in the spectral domain

A recently introduced membrane rheometer consisting of a sample cell covered with two Lorentz-force actuated membranes is modelled using a spectral Fourier transform method yielding a semi-numerical solution. This solution 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 behaviour of the system under varying setup parameters in order to obtain an optimum setup for the given measurement problem.
