 :numref:`cylinder_Ascan_results` shows the time history of the electric and magnetic field components and currents at the receiver location. The :math:`E_z` field component can be converted to voltage which represents the A-scan (trace). The initial part of the signal (<1.5 ns) represents the direct wave from transmitter to receiver. Then comes the reflected wavelet from the metal cylinder.
