A novel millimeter-wave beam-steering technique using a dielectric-image-line-fed grating film
(Texas A&M University, 2001)
This thesis introduces a novel, broadband, low-cost technique for beam steering at millimeter-wave frequencies using a moveable grating film fed by dielectric image line. An excellent radiation pattern is maintained over ...
Behavioral modeling and digital calibration of pipeline analog to digital converters
(Texas A&M University, 2001)
This research focuses on digital calibration of pipeline analog to digital converters (ADCs) and also modeling of error sources and design parameters of pipeline ADCs. Modern applications such as communications systems ...
Spark-plug-mounted fiber optic sensor for measuring in-cylinder pressure in engines
(Texas A&M University, 2001)
A new design for an in-cylinder fiber Fabry-Perot interferometer (FFPI) pressure sensor suitable for automotive engines has been investigated experimentally. The FFPI sensor consists of a single mode fiber containing two ...
