Abstract:

Time-domain dipole antenna array studies conducted at the Electromagnetic Effects Laboratory of the Harry Diamond Laboratories for application to large scale nuclear electromagnetic pulse EMP simulation are described. Analytically and experimentally derived EMP environments for a single-dipole antenna are compared with corresponding data for multiple element broadside and collinear dipole antenna arrays. The multiple-element concept is studied as a technique for eliminating the need for extremely high voltages in the single element-type nuclear EMP simulators by substituting the superimposed electromagnetic fields radiated by several lower voltage sources to obtain the equivalent EMP environment. Experimentally measured input impedances are compared with the results from classical antenna theory to determine the effects of mutual coupling between elements in the array configurations.
