A Novel Device for In-Vitro Electromagnetic Modulation

Eckert B., Truong H., Kim H., Izadjoo M., Trideum Biosciences and ChiScan, US

Our in-vitro experiments with cold plasma discharge have demonstrated frequency dependent modulation effects. If a large number of cold plasma discharges with different modulation frequencies can be generated at the same time, the time required [...]

Gentle Micropump based on Microelectromagnetic Actuator

Al-Halhouli A.T., Waldschik A., Kilani M.I., Büttgenbach S., Technische Universität Braunschweig, DE

This work presents the fabrication and development of a new multifunction micropump based on integrated electromagnetic microactuator. The novel design consists of a fluidic chip, two microfabricated polymer magnets and chip cover. These components form [...]

Efficient Full-Wave Modeling of Electromagnetic Field Propagation Through Micro-Optical Link

Sikorski Z., Turowski M., Przekwas A.J., CFD Research Corporation, US

Low dimensions of contemporary micro-optics imply the necessity of inclusion of vector diffraction effects into optical models. Classical geometrical optics and Gaussian beam calculation approaches are too coarse approximations. They do not properly take into [...]

Structural Analysis of a Magnetically Actuated Silicon Nitride Micro-Shutter for Space Applications

Loughlin J.P., Fettig R.K., Moseley S.H., Kutyrev A.S., Mott D.B., NASA/Goddard Space Flight Center, US

Finite element models have been created to simulate the electrostatic and electromagnetic actuation of a 0.5mm silicon nitride micro-shutter for use in a space-based Multi-object Spectrometer (MOS). The micro-shutter uses a torsion hinge to go [...]
