Ultra-Wideband Antennas and Propagation. Volume 4: Impulse PropagationMeasurements of Water, Dry Sand, Moist Sand, and Concrete

摘要

In this report we continue the measurement and analysis of the complex dielectricconstant of water that was begun in Volume 3. Furthermore, we provide measurements and analyses of dry sand, moist sand, and concrete. We also fit Debye and Lorentz models to the measured dielectric constant curve using a least mean square algorithm. Finally, we calculate how impulses with various pulse widths would propagate through these media.
