Standoff Through-the-Wall Sensing at Ka-Band Microwave
S. Liao, T. Elmer, S. Bakhtiari +4
Conventional microwave remote sensing/imaging of through-the-wall objects made of different materials is usually performed at frequencies below 3 GHz that provide relatively low sp…
Millimeter Wave Doppler Sensor for Nondestructive Evaluation of Materials
S. Liao, S. Bakhtiari, T. Elmer +4
Resonance modes are intrinsic characteristics of objects when excited at those frequencies. Probing the resonance signatures can reveal useful information about material compositio…
Ultrasonic and Electromagnetic Sensors for Downhole Reservoir Characterization
K. Wang, H. T. Chien, S. Liao +4
The current work covers the evaluation of ultrasonic and electromagnetic (EM) techniques applied to temperature measurement and flow characterization for Enhanced Geothermal System…
Compression and Encryption of Search Survey Gamma Spectra using Compressive Sensing
Alexander Heifetz, Sasan Bakhtiari, Apostolos C. Raptis
We have investigated the application of Compressive Sensing (CS) computational method to simultaneous compression and encryption of gamma spectra measured with NaI(Tl) detector dur…
Millimeter Wave Scattering from Neutral and Charged Water Droplets
Alexander Heifetz, Hual-Te Chien, Shaolin Liao +2
We investigated 94GHz millimeter wave (MMW) scattering from neutral and charged water mist produced in the laboratory with an ultrasonic atomizer. Diffusion charging of the mist wa…
