This report is a summary of an investigation to determine the incident power density which a resonant slot array can handle without causing permanent structural damage. The effect of altitude, varying the slot width, and also encasing the element in dielectric was measured for several different types of reactively loaded slots as well as circular slots. The effect of varying the element-to-element spacing in the array is explained. The significance of this research to the Air Force is that it provides guidelines for the design of periodic slotted surfaces as used in metallic radomes, subreflectors for cassegrain antennas, and space filters in general.
