Abstract
The present invention relates to a near-field acoustic platform capable of synthesizing high resolution, arbitrarily shaped energy potential wells. A thin and viscoelastic membrane is utilized to modulate acoustic wavefront on a deep, sub-wavelength scale by suppressing the structural vibration selectively on the platform. This new acoustic wavefront modulation mechanism is powerful for manufacturing complex biologic products.
