Experimental and numerical analysis on PCB coupling in non uniform field environment

Abstract

HPM and UWB pulses are capable of disrupting signal processing or even destroying semiconductor structures. Hence, it is useful to estimate the induced voltage levels on printed circuit boards (PCB) in response to different excitation signals. The considered PCB is integrated within a missile-like cylindrical structure, called GENEC, and is equipped with differential sensors to measure the E- and Hfield above the PCB. Standard transmission line theory is applied to develop a SPICE model that calculates the terminal voltages at the transmission line loads.
