TRANSVERSE ELECTROMAGNETIC CELLS ADAPTED FOR ELECTROMAGNETIC PULSE TESTING

摘要

A transverse electromagnetic (TEM) cell adapted for electromagnetic pulse (EMP) testing, comprises an adapter assembly at each of the tapered ends of the metal shielded enclosure for enabling the cell, including the connectors, to withstand the high voltage pulse of EMP testing while maintaining the continuity of the characteristic impedance. The adapter assembly at each end of the cell comprises outer and inner electrical conductors connected to the shielded enclosure and septum plate, respectively, and an insulating member which includes a first insulating section between the inner and outer conductors, and a second insulating section comprised of a plurality of inclined plates between the tapered end of the shielded enclosure and the septum plate. The adapter assembly at one end is to be connected either to an EMP generator or, with a slight modification, to a standard radio-frequency, continuous-wave generator; and the adapter assembly at the opposite end is to be connected to a load.
