Portland cement concrete (PCC) began to be used as a surface or wearing course for pavements in the United States in the early 1900s. The joint sealant or filler materials used during this early construction period were typically sand, tar paper, coa

The changes in input impedance for a simple antenna or transmission line located over a soil containing a conducting object are examined near antiresonance. The near-field coupling of the underground object to the antenna or transmission line is inve

When utilizing an antenna over ground as a near-field probe for detecting underground conducting objects, maximizing the variation in the antenna input impedance due to the buried object is the primary concern. Using the example of a horizontal dipol
