Metal detector coil design has been matured to great extent over the years. However, vehicle mounted or remotely operated metal detectors require different specifications and these specifications dictate multiple transmit and receive coils operating in various settings. Unlike handheld operation, detector is more susceptible to metallic body of the vehicle. Moreover, ground calibration is also different than handheld devices. Coil geometries and intercoupling between them play a significant role in system design and performance. In this study, we study different coil geometries for vehicular applications. Starting from well-known co . . .il geometries, we placed coils on dry, wet and ferrous soil to understand the interaction mechanism. Simulation studies are performed in frequency domain but the results are all applicable to time domain pulse based detector systems. © 2014 SPIE Daha fazlası Daha az

Absorption of average 10 nm size TiOnanoparticles deposited on glass surfaces as a thin film using convective assembly technique and drop-casting is studied in the millimeter wave range from 26 GHz to 40 GHz. The millimeter wave responses of the fabricated samples were obtained using a vector network analyzer. Reflection properties of the prepared samples were also measured. Absorption and reflection of TiOnanoparticles were more pronounced between 35 GHz and 40 GHz compared to glass-only sample. © 2012 Mehmet Ali Yesil et al.
