The rhombic EMP simulator
Abstract
A complete analysis has been carried out of the twoconductor rhombic antenna as an EMP simulator. The distribution of current along the conductors and the electric field in the working space bounded by rhombic wires have been determined at low, middle, and high frequencies. The analysis indicates that, at low frequencies, when the termination is the characteristic impedance, a travelingwave current with very low standingwave ratio propagates along the wires of the rhombic structure; but it is very sensitive to the load. As the frequency is increased, the standingwave ratio also increases somewhat and it becomes less sensitive to the load. The electric field in the working space exhibits a reasonably constant amplitude with a standingwave ratio of 1.5 or lower at all three frequencies.
