Design and construction of an asymmetrical bounded wave EMP simulator with distributed terminators

An asymmetrical flat-plate guided-wave EMP simulator (MDES-60) with distributed terminators, which is mainly used for short-line test, has been designed and constructed. The volume between two parallel plates is 5 m long, 2 m wide and 1 m high. The whole simulator positioned above a concrete support is 1.5 m high. The design has been optimized by means of reducing the obliquity, widening the bottom plate and tuning the distributed terminator. The improvements allow a good E-field shape and uniformity inside the working volume. This simulator can simulate several kinds of EMP waveforms as defined by IEC61000-2-9, Bell laboratory and standard in 1976 publication, with the peak E-field strengths of 15~60 kV/m available, when being energized by corresponding transient pulse source.
