Projectile vibration analysis of an electromagnetic launcher
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A novel method for the calibration of accelerometers using an electromagnetic launcher (EML) has been investigated by the University of Missouri. The calibration process utilized...
Experimental evaluation of characteristic temperature with varying duty cycles in 2μm vertical cavity surface emitting lasers due to external optical pumping
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Vertical cavity surface emitting lasers (VCSELs) are of interest due to their small size, low cost, tunability, and excellent beam quality. Moreover, the near infrared is one...
Design and application of conformal patch antenna for near-field imaging and object detection
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Compact and low cost planar and conformal patch antennas were designed, fabricated and analyzed for ultra-wideband characteristics. It was also demonstrated through experiment...
PIN photodiode controlled class E microwave power amplifier
(University of Missouri--Columbia, 2012)
