Executive Summary
This note documents high-power electromagnetic (HPEM) pulse and swept continuous wave (CW) testing conducted at an underground Swiss Civil Defense test-bed facility in Spiez, Switzerland. Using a parabolic Impulse Radiating Antenna (IRA) driven by a 2.8 kV sub-nanosecond pulser and a network analyzer, internal electromagnetic field penetration and induced currents on utility cables were characterized. The study also analyzes ground-reflection wave propagation over lossy earth and validates the equivalence of transient and frequency-domain transfer function methodologies.

Abstract
This note describes measurement results from a Swiss test-bed facility in Spiez, Switzerland, for responses to high-power electromagnetic (HPE) environments. The test data was gathered for both pulse and CW illuminations. The pulse illumination was accomplished by using the Swiss Impulse Radiating Antenna (Swiss IRA) system, fed by a commercial pulse generator. CW measurements were obtained using the same antenna and a network analyzer and wideband amplifier. This antenna and its characteristics are briefly discussed, and samples of the results of the measurements obtained in this test program are illustrated.
