Study of a Scale Model of a Common Carrier Communication Station.
Abstract
A 1/40 scale model of the AT and T communications station at Vega, Texas was constructed using electromagnetic scaling principles and incorporating features from Midlothian that were not present at Vega. The model was illuminated, with the electromagnetic pulse (EMP) time base scaled to 1/40 of the actual time. The illumination simulated (1) the Radiating EMP Simulator (RES) waveform, (2) the SAFEGUARD SYSTEM MASTER PLAN (SSMP) 4.00A waveform referred to in the report as the High Altitude EMP (HEMP) waveform, and (3) an impulse-type waveform. The RES illuminations were vertically polarized, with the angle of incidence at 90 degrees (grazing). HEMP and impulse-type illuminations were vertically polarized for an incidence angle of 90 degrees, both vertically and horizontally polarized for an incidence angle of 65 degrees, and horizontally polarized for an incidence angle of 0 degrees. Waveform records were obtained for penetration currents into the building from external structures and for surface currents on the building walls resulting from the illuminations.
