MIX MATRIX MODELING OF TWO - PORT SURFACE ACOUSTIC WAVE DEVICE FOR PROTEIN CHARACTERIZATION

Presented research describes finite element modeling of Two - Port surface acoustic wave devices used for protein characterization. Typical SAW device converts electrical energy into a mechanical wave on a single crystal substrate. It provides very complex signal processing in a very small volume. It is estimated that approximately 4 billion SAW devices are produced each year. SAW devices are sensitive to temperature, stress, pressure, liquids, viscosity and surface effects, a wide range of sensors are possible. The devices are small, rugged, stable, and capable of high volume low cost production. Research focus is on studying finite element modeling of this devices based on mix matrix methods to characterize conductance, susceptance , viscosity, and other properties of protein samples, like albumin using Two - Port SAW related resonator
