The propagation of high-power microwave pulses through the atmosphere is often modeled with time-dependent fluid or kinetic codes that require a fine mesh of range and time points. The computational time to run these codes precludes their use to determine the optimum pulse characteristics and propagation paths for delivery of a desired fluence to a specified target. In this work, a universal, parameterized scaling law for microwave-induced air breakdown is integrated into the SNEAKY model to produce a new microwave propagation code, SNEAKY-II. It estimates microwave fluences to within 1%--13% agreement with the more elaborate time-dependent fluid codes while running a hundred to several thousand times faster. The purpose of this report is to document the SNEAKY-II code, complete with benchmarking and specifications of the inherent limitations. 5 refs., 17 figs., 3 tabs.
