Measurements of Short-Pulse Propagation Through Concrete Walls
We recently performed a series of experimental measurements of transient electromagnetic (EM) propagation through two different concrete walls. Several different short-duration pulses were used for the incident radiation, with frequency content from VHF to 20 GHz. Both walls were 30 cm thick, with three internal layers of reinforcing steel bars. For this particular set of data, the incident wave polarization was vertical linear only. Corroborating swept-frequency measurements were made with a vector network analyzer.
