Metasurface based uncooled Sixgeyo1-x-y microbolometer for infrared detection
(University of Missouri--Columbia, 2022)
on the geometry of the metasurface material. The inclusion of the metasurface permits engineering the IR absorptance with respect to wavelength. Absorption by the metasurface eliminates the need for a 1/4-wave resonant cavity under the microbolometer. In addition...
Metasurface integrated uncooled silicon germanium oxide microbolometers for long wavelength infrared detection
(University of Missouri--Columbia, 2022)
]m. The voltage noise power spectral density (PSD) of the fabricated devices were reduced by annealing the devices in vacuum. In addition, the measured TCR, thermal conductance Gth, and absorptivity were 2.5 percent/K, 4.44x10-8 W/K, and 39 percent, respectively...
Impedance and plasmonic based MEMS sensors for chemical and biological applications
(University of Missouri--Columbia, 2020)
that increased the strength of the measured signal by a factor between 4 and 6.25, high sensitivity of 3 cell/ml and detection time of less than 1 hour. The second project is implementing a fiber optic based chemical sensor, which consists of a thin film metal...
Optical and impedance based sensors for chemical/biological and foodborne pathogens applications
(University of Missouri--Columbia, 2023)
. MPL with off-exposure technique was also exploited to create 3-disks and 4-disks groups which would increase the total number of disks pattern in the core area of the fiber endface, decreasing the periodicity between fabricated disks. The sensor...
Design and fabrication of one and two axis nickel electroplated micromirror array
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] MEMS based micromirror devices are gaining importance at a steady pace in the applications related to optical communications and display technology. ...
